How to Add Side Guards to Conveyor Systems

If you've ever walked through a busy warehouse or manufacturing floor, you've probably seen conveyor systems hard at work—moving boxes, parts, and products from one station to the next like a well-choreographed dance. But even the most reliable conveyor can hit a snag if products slip, tip, or fall off the edges. That's where side guards come in. These simple yet critical additions not only protect your inventory from damage but also keep workers safe by preventing tripping hazards or collisions with loose items. In this guide, we'll walk through how to add side guards to your conveyor system step by step, from assessing your needs to installation and maintenance. Let's dive in.

Why Side Guards Matter: Safety, Efficiency, and Peace of Mind

Before we get into the "how," let's talk about the "why." Side guards might seem like a small detail, but they play a big role in keeping your operation running smoothly. Here's why they're worth the effort:

Product Protection: Even a minor bump or jostle can send a fragile component or a stacked box tumbling off the conveyor. Side guards act as a barrier, keeping items centered and secure—saving you from costly rework or replacements.
Worker Safety: Loose items on the floor are a tripping risk, and falling products can injure employees nearby. Side guards reduce these hazards, creating a safer workspace for everyone.
Regulatory Compliance: Many industries (like manufacturing, logistics, and food processing) have safety standards that require conveyor systems to include protective barriers. Adding side guards helps you stay compliant and avoid fines.
Efficiency Boost: When products stay on track, you spend less time stopping the line to retrieve fallen items or fix jams. That means faster throughput and happier team members who aren't stuck cleaning up messes.

Pro Tip: If your conveyor handles small parts (like electronics components) or irregularly shaped items, side guards are non-negotiable. These items are more likely to slip through gaps in unguarded conveyors, leading to lost inventory or equipment damage.

Step 1: Assess Your Conveyor System

Before you start shopping for materials, take time to evaluate your conveyor. Not all systems are the same, and the right side guards depend on your conveyor's design, the products you move, and your workspace layout. Here's what to check:

Measure the Basics

Grab a tape measure and note these key details:

Length: How long is the conveyor section you need to guard? This will determine how much material you'll need.
Width: The distance between the conveyor's edges (e.g., the roller track or belt). Side guards should extend just high enough to contain your tallest or widest product—usually 2–6 inches, depending on what you're moving.
Height: If your conveyor is elevated (e.g., mounted on a frame), measure from the floor to the conveyor surface. This helps when choosing mounting hardware.

Check the Conveyor Type

Conveyors come in different styles, and each may need slightly different side guards. The most common types include:

Roller Track Conveyors: These use a series of rollers (like roller track or plastic roller track guide rail ) to move items. Side guards here need to be low-profile enough to avoid interfering with roller movement but sturdy enough to block items from sliding between rollers.
Belt Conveyors: Flat belts require side guards that sit flush with the belt edge to prevent snagging. Avoid sharp edges that could damage the belt over time.
Chain Conveyors: Used for heavy loads, these have metal chains that pull items along. Side guards here should be extra durable (think steel or thick aluminum) to withstand impacts.

Identify Potential Obstacles

Look for parts of the conveyor that might complicate installation: curves, merges, motors, or existing brackets. For example, a curved roller track section will need flexible or angled side guards, while a straight section can use simple straight barriers. Note these areas—you may need custom cuts or adjustable brackets to work around them.

Step 2: Choose the Right Materials

Side guards are only as good as the materials they're made from. The best choice depends on your budget, the weight/size of your products, and your environment (e.g., wet, dusty, or clean rooms). Here's a breakdown of common options:

Material	Pros	Cons	Best For
Aluminum Profile	Lightweight, corrosion-resistant, easy to cut/assemble with accessories like brackets or joints.	Slightly more expensive than plastic; may bend under heavy impacts.	Medium-weight products, clean environments (e.g., electronics assembly), or conveyors that need frequent reconfiguration.
Plastic (e.g., PVC or Polypropylene)	Budget-friendly, lightweight, no rust risk; available in flexible or rigid options.	Less durable for heavy loads; can warp in high temperatures.	Light items (e.g., small boxes, packages), temporary setups, or low-budget projects.
Steel	Heavy-duty, impact-resistant; ideal for large or heavy products.	Heavy, prone to rust (unless coated); harder to cut/modify on-site.	Industrial settings, metal parts, or conveyors moving pallets/heavy machinery components.
Wire Mesh	Allows visibility (so workers can see products moving); lightweight.	Not great for small parts (they can slip through gaps); less sturdy than solid barriers.	Conveyors where visibility is key (e.g., quality control stations) or large, bulky items.

For most warehouses and manufacturing facilities, aluminum profile is a top pick. It's strong enough for everyday use, resists rust (important in humid environments), and pairs well with standard conveyor components—like aluminum brackets or plastic roller track guide rail. Plus, aluminum profiles are easy to cut with a hacksaw or miter saw, making on-site adjustments a breeze.

Step 3: Gather Tools and Materials

Once you've picked your material, it's time to round up the tools and supplies you'll need. Here's a checklist to get you started:

Tools

Tape measure and pencil (for marking cuts and mounting points)
Hacksaw, miter saw, or PVC cutter (depending on your material)
Drill and drill bits (for making holes in the conveyor frame or aluminum profile)
Screwdriver or wrench (to tighten brackets and fasteners)
Level (to ensure side guards are straight and even)
Sandpaper or deburring tool (to smooth rough edges after cutting)

Materials

Side guard material (e.g., aluminum profile, plastic strips, or steel bars)
Mounting brackets (choose ones that fit your conveyor frame—aluminum brackets work well with aluminum profiles)
Fasteners (screws, bolts, or clips; stainless steel is best for rust resistance)
End caps (to cover sharp edges on aluminum or steel guards—safer for workers!)
Adhesive (optional, for lightweight plastic guards on smooth conveyor frames)

Pro Tip: Buy a little extra material (5–10% more than your measured length) to account for mistakes or unexpected cuts. It's better to have leftover aluminum profile than to run short mid-project!

Step 4: Install the Side Guards

Now for the hands-on part! Follow these steps to install your side guards safely and effectively:

1. Prep the Work Area

Start by powering off the conveyor—never work on a moving system! Clear the area around the conveyor of debris, tools, or tripping hazards. If you're working on an elevated conveyor, use a sturdy ladder or platform (and have a helper spot you).

2. Cut the Guards to Length

Measure and mark your side guard material (e.g., aluminum profile) to match the conveyor length you measured earlier. Use a saw to cut straight lines—for aluminum, a miter saw with a metal-cutting blade works best. After cutting, use sandpaper to smooth any sharp edges (this prevents snags and cuts).

3. Mark Mounting Points

Lay the cut guard along the edge of the conveyor to test the fit. Then, mark where you'll attach the brackets. Space brackets every 18–24 inches for stability—closer if you're using lightweight materials or guarding heavy items. Use a level to ensure the guard is straight before marking; uneven guards can cause products to catch or tip.

4. Drill Holes (If Needed)

If your conveyor frame or guard material needs holes for screws, drill them now. For aluminum profile, use a drill bit slightly smaller than your screws to prevent stripping. For plastic, start with a small pilot hole to avoid cracking.

5. Attach the Brackets and Guards

Secure the brackets to the conveyor frame first, then attach the side guard to the brackets. Use screws or bolts tight enough to hold the guard firmly, but not so tight that you warp the material (especially plastic). If you're using aluminum profile, you can also use T-slot nuts and bolts to slide brackets into the profile's grooves—this makes adjustments easier later.

6. Add End Caps and Finishing Touches

Snap or glue end caps onto the top and bottom of the guards to cover sharp edges. If your conveyor has curves, cut the guard at an angle or use flexible plastic to follow the bend. Finally, give the guard a gentle shake to test stability—if it wobbles, tighten the brackets or add extra supports.

Step 5: Test and Adjust

You're almost done! Before firing up the conveyor, test the guards to make sure they work as intended:

Manual Test: Push a sample product along the conveyor by hand. Does it stay centered? Do the guards block it if you gently nudge it toward the edge?
Powered Test: Turn on the conveyor at a slow speed and run a few products through. Watch for snags, rubbing, or items getting stuck between the guard and the roller track. If something catches, stop the conveyor and adjust the guard's position (e.g., raise it slightly or move it closer to the edge).
Safety Check: Ensure there are no gaps between guards (especially at joints) where small items could slip through. Also, confirm that guards don't extend beyond the conveyor's end—this could create a collision hazard.

Don't worry if you need to tweak the guards a few times—every conveyor and product is different, and small adjustments will make a big difference in performance.

Step 6: Maintain Your Side Guards

Side guards aren't "set it and forget it"—they need regular care to stay effective. Add these tasks to your maintenance checklist:

Weekly Inspections: Check for loose brackets, cracks in plastic guards, or bent aluminum profile. Tighten screws or ｒｅｐｌａｃｅ damaged parts as needed.
Cleaning: Wipe down guards to remove dust, grease, or debris—this prevents buildup that could make products stick or slip.
Adjustments: If you start moving new products (taller, wider, or heavier), re-evaluate guard height and sturdiness. You may need to add extensions or switch to a stronger material.

Final Thoughts: Guards That Grow With Your Operation

Adding side guards to your conveyor system is one of those small investments that pays off big—in safer workers, fewer damaged products, and smoother operations. Whether you're using aluminum profile for a sleek, adjustable setup or budget-friendly plastic for a quick fix, the key is to start with a clear assessment of your needs and take the time to install them properly.

And remember: your conveyor system is always evolving. As you add new products, expand your facility, or upgrade equipment, revisit your side guards to make sure they're keeping up. With a little care, they'll protect your operation for years to come.
