The Simpson Strong-Tie ARC37-RP25 Adhesive Retaining Cap is a precision-engineered plastic accessory from Simpson Strong-Tie designed to make overhead, upwardly inclined, and horizontal anchor installations cleaner and more accurate. By fitting over a 1/2 in. drilled hole, the cap prevents anchoring adhesive from running out during installation while simultaneously centering a 3/8 in. threaded rod or #3 rebar dowel in the hole - making it an essential component wherever precise anchor placement is required.

Frequently Asked Questions

What is the purpose of the slit in the ARC37 adhesive retaining cap?

The slit in the cap allows the threaded rod or rebar dowel insert to pass through during installation while still containing the anchoring adhesive inside the drilled hole, preventing it from running out - especially critical in overhead and inclined orientations.

Can the ARC37 retaining cap support the weight of the anchor in overhead installations?

No. Adhesive retaining caps are not designed to support the weight of the anchor. In overhead installations, it is advisable to provide an adequate means of anchor support during the adhesive cure time.

Which Simpson Strong-Tie adhesives are compatible with the ARC37 retaining cap?

The ARC37 retaining cap works with any Simpson Strong-Tie anchoring adhesive, providing broad compatibility across the Simpson Strong-Tie adhesive anchor product line.

Can the ARC37 be used with the Simpson Strong-Tie Piston Plug Delivery System?

Yes. ARC adhesive retaining caps may be used in conjunction with the Simpson Strong-Tie Piston Plug Delivery System, offering a compatible and streamlined approach to adhesive anchor installations.
