Dust left in a drilled hole weakens the bond between adhesive and concrete. The ETB10 is a long, reusable nylon-bristle brush on a twisted wire handle, sized for 1" to 1-1/8" holes and long enough to reach the bottom of deep embedments.
The ETB10 suits everyday, non-specified anchoring such as Strong-Bond™. For installations that must comply with the ICC-ES reports for SET-3G™ or AT-3G™, use the listed ETBS-series wire brush on an ETBS-TH T-handle:
The ETBS-TH T-handle with a brush head reaches holes up to 13-1/2" deep; for deeper holes, add an ETBS-EXT 12" extension. Brush heads, T-handle and extensions are sold separately.
