Frequently Asked Questions

Which adhesive must be used with the AWS623P screen tube?

The AWS623P is an acrylic screen tube and must be used exclusively with Simpson Strong-Tie AT-XP acrylic adhesive. Screen tubes are designed for a specific adhesive type, and using an incompatible adhesive can compromise anchor performance.

What is the purpose of the flanges on the Opti-Mesh screen tube?

The flanges on the screen tube are designed to prevent it from slipping into over-drilled holes, helping to ensure the tube stays properly positioned during the adhesive dispensing process.

Why should I use a plastic Opti-Mesh screen tube instead of a steel screen tube?

The Simpson Strong-Tie Opti-Mesh plastic screen tube provides the economical advantage of a plastic screen tube while delivering superior performance to both steel screen tubes and competitive plastic screen tubes. Its formula-specific woven mesh design precisely controls adhesive flow for optimal anchor performance.

What hole size is required for the AWS623P screen tube?

The AWS623P requires a 7/8 in. drilled hole to accommodate the screen tube, which is designed for use with 5/8 in. diameter rod. The integral cap displays the correct drill bit and rod diameter for easy reference during installation.
