Now for the main event: installing the
Turning Angle Code 3030. Follow these steps carefully, and you'll have a secure, professional-looking joint in no time. We'll take it slow, explaining each part so even if you've never held a hex key before, you'll feel confident.
Step 1: Align the Turning Angle Code with the Marked Position
Place the
Turning Angle Code 3030 on the 3030
aluminum profile, lining up its screw holes with the T-slot(s) you marked earlier. The angle code has two "arms"—each arm should sit flat against one side of the profile (for a right-angle joint, one arm will attach to the vertical profile, and the other to the horizontal profile). Make sure the angle code is centered on the profile's width (30mm) so it doesn't hang over the edge. If your project uses a
gusset alp 3030 (a triangular bracket that reinforces corners), set it aside for now—we'll add it after the angle code is secured.
Step 2: insert the Screws into the Angle Code Holes
Take your M5 or M6 socket head cap screws (check the angle code's packaging for the recommended size—most 3030 angle codes use M5 screws) and insert them through the holes in the angle code. Push them gently into the T-slot of the
aluminum profile. You should feel slight resistance as the screw's threads catch the T-slot nut inside the profile (if your profile doesn't have pre-installed T-slot nuts, you'll need to insert them into the T-slot first—slide the nut into the slot and align it with the angle code's hole). Don't tighten yet—just hand-screw them until they're snug enough to hold the angle code in place.
Step 3: Tighten the Screws Gradually (Don't Over-Tighten!)
Grab your hex key and start tightening the screws. Here's the golden rule:
tighten them gradually, alternating between screws
. For example, if the angle code has two screws per arm, tighten the first screw a little, then the second, then go back and tighten the first more, and so on. This ensures even pressure and prevents the angle code from shifting. How tight is "tight enough"? You'll feel resistance, and the angle code shouldn't wiggle when you tug it gently. Stop when the screw head is flush with the angle code's surface—over-tightening can strip the threads in the T-slot nut or warp the angle code, weakening the joint. If you hear a "creaking" sound from the aluminum, you've gone too far—loosen it slightly.
Step 4: Check Alignment with a Spirit Level
Now that the angle code is attached to one profile, it's time to connect the second profile (for a corner joint). Hold the second 3030 profile against the other arm of the angle code, aligning it with your project's design (e.g., vertical and horizontal for a shelf). Mark the screw holes on the second profile, insert screws, and tighten as in Step 3. Once both profiles are attached, place your spirit level along the top of the horizontal profile and the side of the vertical profile. The bubble should sit in the center—if it's off, gently loosen the screws, adjust the profile until the bubble is centered, then retighten. This step ensures your structure is straight, not leaning, which is critical for stability (no one wants a shelf that tilts!).
Step 5: Add Optional Accessories (e.g., Gusset Alp 3030)
For projects that will hold heavy loads (e.g., a
workbench with tools or a material rack with boxes), consider adding a
gusset alp 3030
to the corner. A gusset is a triangular plate that fits between the two profiles, reinforcing the joint by distributing weight across a larger area. To install it: place the gusset against the inside corner where the two profiles meet, align its holes with the T-slots, insert screws, and tighten as before. Gussets are optional but highly recommended for high-stress joints—they turn a "good" joint into a "great, long-lasting" one.
Step 6: Inspect the Joint for Stability
Give the joint a gentle shake or tug. It should feel solid—no movement, no creaking, no loose screws. If it wobbles, check: Are the screws tight enough? Did the angle code shift during tightening? Is the profile aligned correctly? Fix any issues before moving on to the next corner. Remember, a little extra time here prevents big problems later!
