Stanley Bostitch CAPPAK-5M Cap and Staple Pack

Product Description

The STANLEY BOSTITCH CAPPAK-5M is a combination consumable pack supplying 5,000 Bostitch plastic caps and 5,000 Bostitch staples in a single box. The staples are the SL50351G style at 1 inch in length, sized specifically for cap stapling applications in roofing, housewrap, and underlayment fastening. This pack is intended for trade professionals who need to keep a Bostitch SB150S or BC-1 cap stapler running without sourcing caps and staples separately. Each component is OEM-matched to the tool, ensuring proper feed and consistent drive performance on the job site.

Cap staple packs like the CAPPAK-5M are used in residential and light commercial construction where plastic cap fasteners are required to secure roofing felt, synthetic underlayment, building wrap, and insulation board. The 1-inch SL50351G staples paired with the matching plastic caps distribute clamping force across the cap face, reducing material tear-through. This pack is sold by the box and is a standard replenishment item for crews running the Bostitch SB150S or BC-1 cap stapler on roofing or envelope work.

Installation Notes

Cap staple packs are loaded by roofing mechanics and general construction tradespeople familiar with pneumatic or manual cap staplers. Before reloading, disengage the tool from the air supply or confirm the manual stapler is in the safe position before opening the magazine. Follow the tool manufacturer's loading instructions to seat the staple stick and cap stack correctly. Improper loading can cause jams or misfires that damage both the tool and the substrate material.
