## Summary

Hidden clips should be approved for the exact board groove, supporting material and screw combination. Similar-looking components are not proof of compatibility.

## Practical method

Compare the clip geometry, screw engagement, corrosion specification and intended movement function. A substitute can grip too tightly, support too little of the groove or use the wrong screw for the joist. Ask the supplier for written compatibility before bulk purchase. Build a small representative assembly and check removal access as well as installation. For a repair to an older deck, identify the original system first; a newer clip sold for the same brand may still belong to another profile generation.

## Planning and verification

Compare complete systems for the stated use, including supporting structure, connections, drainage and maintenance access. Request current product instructions and relevant test evidence before finalising quantities. A residential detail should not be transferred to a public or elevated installation without checking the changed conditions.

## Handover and maintenance

Record the selected profile, batch, approved drawings and maintenance owner. Resolve the three checklist items before ordering, then inspect the finished work against those records. Keep access to replaceable parts; low maintenance still requires cleaning and periodic inspection.

## Can you mix hidden clips from different WPC systems? — What should be confirmed before ordering?

Hidden clips should be approved for the exact board groove, supporting material and screw combination. Similar-looking components are not proof of compatibility. Confirm the three project checks below with the supplier and the responsible designer. A sample establishes appearance, not approval of the complete installation. Exact profile match; Approved screw and joist; Replacement compatibility
