Dust left in a drilled hole weakens the bond between adhesive and concrete. The ETB6 is a reusable nylon-bristle brush on a twisted wire handle, sized for 1/2" to 3/4" holes, for scrubbing drilled holes clean before you inject adhesive.
The ETB6 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.
