The Simpson Nylon Hole-Cleaning Brush for Rebar, 1/2-3/4" Hole Diameter is a purpose-built hole preparation tool designed to thoroughly clean drilled holes before adhesive anchor installation. Engineered with a nylon brush head and extended useable length, this brush ensures the full depth of each drilled hole is properly cleared of debris and dust - a critical step for achieving reliable adhesive bonding performance when installing rebar anchors.

Key Features

• Nylon brush head construction - delivers effective scrubbing action to remove loose material from drilled holes, helping adhesive make full contact with the hole wall for a stronger bond
• Longer length and stronger construction - allows the brush to reach the full depth of holes drilled for deeper rebar embedments, so no section of the hole is left uncleaned before adhesive is applied
• Compatible with 1/2" to 3/4" hole diameters - covers the range needed for #3 through #5 rebar anchor sizes, giving installers a single tool that works across multiple common embedment scenarios
• 6-inch useable length - provides the reach required to properly prepare deeper drilled holes, reducing the risk of incomplete hole cleaning that can compromise adhesive anchor performance
• Approved for use with Simpson ET-3G and SET-3G adhesives - ensures compatibility with the specific epoxy systems that require proper hole preparation as part of their installation process

Why This Product

• Built for deeper embedments - the longer length and stronger construction directly address the demands of rebar anchor installations that require greater hole depth, where standard brushes may fall short in cleaning reach
• Optimized for adhesive anchor performance - proper hole cleaning is a required step before applying epoxy adhesive, and this brush is specifically engineered for that preparation task, helping protect the integrity of the finished anchor
• Broad compatibility for rebar work - supporting #3 through #5 rebar sizes and a 1/2" to 3/4" hole diameter range, this brush suits a variety of common structural anchoring applications without requiring multiple different tools
• Matched to Simpson adhesive systems - designed for direct use with Simpson ET-3G and SET-3G epoxy adhesives, so contractors working within those product systems have a brush that aligns with the manufacturer's hole preparation requirements
