Barrel and Wedge Anchors are used to secure roof plates on 15.2mm diameter x 7 wire strand cable bolts. They provide positive support to the rock face at the collar of the hole.
The Barrel and Wedge anchor can be used on one, two or multiple strand (15.2mm) cable bolts in either minicage or plain forms.
Barrel and wedge anchors suit flat plates commonly used for Cable Bolts.
The Barrel and Wedge Anchor can be used to pre-stress cable bolts prior to grouting. They can also be fitted to grouted cable bolts to secure additional mesh or W strap.
The wedge in the anchor has hardened serrations to provide a positive grip on the strand. Each wedge consists of three segments, secured by a ring to ensure wedge alignment and initial clamping.
The barrel is manufactured from toughened steel to resist splitting.
Corrosion protection can be provided on the barrel only by hot dip galvanizing (refer to Section G), or zinc plated to AS 1789-1984.
Packaging
All 16mm expansion shells are contained in cardboard boxes then packed on pallets
