Product Description
Simpson 1" Hole-Cleaning Wire Brush Head for SET-3G is a precision-engineered wire brush head from Simpson designed for cleaning drilled holes prior to adhesive anchor installation. Built to work with Simpson Strong-Tie SET-3G and AT-3G adhesives, this brush promotes proper hole cleaning with fewer brush strokes at embedments up to 20 times the anchor diameter - helping installers achieve reliable, code-compliant anchoring results.
Key Features
- 1-in. brush head for a 1-in. hole diameter - sized precisely for the target bore, ensuring full contact with the hole wall for thorough debris removal on every pass.
- Compatible with 7/8-in. anchors and #7 rebar - covers a common anchor and rebar size, making this brush a practical choice for a wide range of structural anchoring applications.
- 5-in. useable brush length - provides substantial reach within the hole; total usable length can be extended by combining the brush with a T-handle and optional extension (each sold separately).
- Requires T-handle model ETBS-TH (sold separately) - the dedicated T-handle gives installers the grip and control needed to work the brush effectively through the full hole depth.
- Engineered for use with SET-3G and AT-3G adhesives - cleaning the hole with this brush before injection helps the adhesive bond properly, supporting embedment performance at depths up to 20 times the anchor diameter.
