Suggested Fastening Methods

Rawl Spike Installation

Rawls Spike PunchInstallation: Drill a hole into the base material to a depth of at least 60mm.The tolerances of the drill bit used should meet the requirements of ISO/DIN Standard 8035. Blow the hole clean of dust and other material. Drive the Spike through the appropriate mirror face hole (and frame when used) ensuring the head is sitting firmly against the mirror or frame and recessed as shown in the above diagram.

NOTE: Care should be taken not to overdrive the Spike so as to cause damage to the powder coated surface of the frame. Finish off by applying (optional) a bead of non-pick sealant around the mirror or frame and the wall to prevent the secretion of small objects (eg razor blades etc).

DuraVision Rawl Spike Punch: The DuraVision designed punch for inserting spikes can significantly reduce the risk of damaging the mirror face and frame during installation.

 


Torx Screw Installation

Torx ScrewInstallation: It is recommended to use a 3/16” (4.76mm) Straight Shank Tanged Bit to drill the hole. The hole must be at least 2” or 50mm overall depth and free of any debris. By using the #27, 1/4” (6.35mm) Hex Bit the special Hi-Lo thread literally taps into masonry materials. The high,sharp thread with its notched cutting edge cuts deeply and easily. The alternating low thread provides stabilty for fast, accurate driving. Torx Tamperproof masonry screws are the optimal fastening solution for use in concrete, brick, or hollow block.
