UCAN's 1.063 in. OD x 4 in. Stainless Steel-Wire Hole Cleaning Brush provides contractors with a straightforward way to perform the brushing step required when preparing drilled holes for adhesive anchors. Proper hole cleaning helps remove contaminants that can interfere with adhesive contact and anchoring performance, making brush selection an important part of the installation process. This model is part of UCAN's FLO-ROK® hole cleaning brush system and is specifically associated with 1 in. diameter holes, 7/8 in. rod, and 20M rebar. For concrete fastening crews, the SBR 1 offers a dedicated hole-preparation tool that supports consistent installation practices without adding unnecessary complexity to the anchoring process.
