How to use

Mark the fixing position on the masonry surface, then drill a hole with a 5 mm diameter drill bit to at least 45 mm depth. Clean the hole from dust and debris before inserting the wall plug. Place the fixture, align the screw through the fixing and into the plug, then tighten using a Pozidriv screwdriver or compatible bit until the fixing is secure. Avoid over-tightening to prevent damaging the plug or the masonry.

Recommendations

Verify the suitability of the kit for the specific masonry type before installation. For hollow or lightweight substrates, use an appropriate anchor system designed for those materials. When installing load-bearing or safety-critical fixtures, follow relevant building standards and, if necessary, consult a structural professional.
