The Simpson ETB8L ETB 1 in. x 24 in. Nylon Hole-Cleaning Brush from Simpson Strong-Tie is purpose-built for cleaning drilled holes prior to adhesive anchor installation. Designed to work in conjunction with Simpson Strong-Tie adhesives, this nylon hole-cleaning brush helps ensure the thorough hole preparation that reliable adhesive anchor performance depends on - making it an essential accessory for any anchoring application where surface cleanliness directly affects bond integrity.

Key Features

• Twisted wire handle with nylon bristles for strength - delivers firm, consistent scrubbing action inside the drilled hole without bristle collapse, so debris and dust are cleared effectively every time
• Compatible with holes from 13/16 in. to 7/8 in. in diameter - fits the range needed for 3/4 in. and #6 bolt or rod anchor applications, giving you the right fit for proper wall-to-bristle contact
• Useable length of 23 in. - provides ample reach for cleaning deeper drilled holes where shorter brushes fall short
• Sturdy and reusable construction - the durable twisted wire handle resists bending under load, so the brush holds up across multiple hole-cleaning jobs and reduces the need for frequent replacements

Why This Product

• Designed specifically for Simpson Strong-Tie adhesive systems - engineered for use with SET-XP, AT-XP, and ET-HP adhesive anchors, meaning the brush geometry and bristle density are matched to the hole-prep requirements those systems demand
• Reaches where standard brushes cannot - a 23 in. useable length handles deep anchor holes that shorter, general-purpose cleaning brushes cannot adequately reach, helping maintain consistent adhesive performance at any depth
• Reusable design keeps job site costs in check - the sturdy twisted wire handle and durable nylon bristles are built to withstand repeated use, so one brush goes a long way across multiple anchor installations
• Made in the United States - manufactured domestically under Simpson Strong-Tie quality standards, providing confidence in material consistency and workmanship for structural anchoring applications
