- Use a center punch to prevent drill bit slippage, especially on metal surfaces.
- Select the correct drill bit size as specified by the bracket manufacturer (typically matching the bolt diameter).
- Drill pilot holes slowly and steadily, keeping the drill perpendicular to the surface.
Accurate pre-drilling ensures clean installation, prevents material splitting, and maintains structural integrity.
- Adjusting Bracket Position
Before permanently securing the bracket, test its position to ensure optimal strut performance:
- Temporarily attach the bracket using one fastener to allow slight rotation.
- Maneuver the bracket to achieve the correct angle for full extension and retraction of the gas strut.
- Swivel or articulating brackets offer greater flexibility and should be adjusted so the ball joint moves freely without binding.
- Ensure there is no interference between the strut body and surrounding components during full travel.
Proper angular alignment maximizes force output and extends the life of both the strut and mounting hardware.
- Fixed Bracket Tightening
Once the ideal position is confirmed, secure the bracket firmly:
- Insert all bolts or screws and hand-tighten them initially.
- Use a spirit level or alignment tool to verify the bracket is horizontally or vertically oriented as required.
- Tighten all fasteners gradually in a crisscross pattern to distribute pressure evenly.
- Use a torque wrench if specified to avoid stripping threads or damaging materials.
A securely mounted bracket prevents shifting under load and ensures consistent strut performance.
- Installation of Center-Mounted Brackets
Center-mounted brackets are often used for symmetrical support or single-point applications:
- Position the bracket along the central axis of the moving panel for balanced lift.
- Align the bracket so that the strut will extend parallel to the opening plane.
- Secure using pre-drilled holes and appropriate fasteners for the substrate (e.g., self-tapping screws for plastic, machine bolts for metal).
- Double-check alignment with a level and confirm clearance throughout the full range of motion.
Note: Unlike side-mounted brackets, center mounts may require additional reinforcement due to concentrated stress.
- Attaching Strut End Fittings
With brackets secured, connect the gas struts:
- Insert ball-end fittings into the corresponding socket or clevis pin and secure with a retaining clip or cotter pin.
- For fork or eye-end fittings, align the hole and insert the bolt or pin, then secure with a nut and washer.
- Ensure all connections pivot freely without lateral play or binding.
- Check that dust caps (if present) are intact to protect internal mechanisms from debris.
Never force a connection—misalignment can cause premature wear or strut failure.
- Testing Strut Functionality
The final and most crucial step is functional testing:
- Slowly open and close the panel to assess smoothness of operation.
- Verify the strut supports the panel at various angles, especially at the midpoint and fully open position.
- Listen for unusual noises (clicking, grinding) that may indicate binding or misalignment.
- If resistance or instability occurs, recheck bracket angles and re-adjust as needed.
- Re-tighten any loose hardware after initial use.
Perform multiple test cycles to ensure consistent performance before declaring the installation complete.
