Product Description
Simpson Wire Hole-Cleaning Brush Head for 3/4-in. Holes is engineered specifically for cleaning drilled holes prior to adhesive anchor installation. Designed for use with Simpson Strong-Tie SET-3G and AT-3G adhesives, this brush delivers thorough hole cleaning with fewer brush strokes at embedments up to 20 times the anchor diameter - helping ensure a reliable bond when anchoring #5 rebar and threaded rod.
Key Features
- 3/4-in. brush head sized for 3/4-in. hole diameter - matches the hole precisely for effective wall-to-wall contact and thorough debris removal with every stroke
- Compatible with #5 rebar size - ensures the correct brush-to-hole fit for anchoring #5 rebar, reducing the risk of improper cleaning that can compromise adhesive performance
- 5-in. useable brush length - provides sufficient reach within the drilled hole; total usable assembly length is calculated by adding the brush length to the usable length of the handle and any optional extension used
- T-handle required, sold separately (model ETBS-TH) - keeps the initial purchase cost focused on only the components you need, with the flexibility to pair brushes with handles and extensions already on hand
