The Simpson 12-inch Extension for ETBS-TH T-Handle is a Simpson Strong-Tie accessory built to extend the reach of the ETBS-TH T-handle when cleaning drilled holes prior to adhesive anchor installation. Engineered for use with all sizes of the Simpson Strong-Tie ETBS standard wire hole-cleaning brush, this extension enables thorough hole preparation with fewer brush strokes at embedments up to 20 times the anchor diameter - supporting reliable adhesive anchor performance when used with SET-3G and AT-3G adhesives. The T-handle and brushes are sold separately.

Key Features

• 12 in. extension for the ETBS-TH T-handle - adds significant reach to your hole-cleaning assembly, allowing you to clean deeper drilled holes without changing your setup
• 11-1/2 in. useable length - to obtain total usable reach, add the usable length of the brush, the handle, and this optional extension together, giving you precise control over your assembly configuration
• Compatible with all sizes of Simpson Strong-Tie ETBS standard wire brushes - works across the full ETBS brush range so you are not limited to a single anchor size or application
• Requires the ETBS-TH T-handle (sold separately) - designed to integrate directly into the existing ETBS system, keeping your investment in compatible components consistent
• For use with Simpson Strong-Tie SET-3G and AT-3G adhesives - ensures the wire brush cleaning system meets the preparation requirements for these specific adhesive anchor applications
