Pex Stapler for Wood and Foamboard

Fast, Easy One-Handed, One Stroke Stapling

Designed for use with in-floor radiant heating installations.  This easy-loading and portable manual stapler No. PWS1, with magazine feed, operates from a standing position to quickly secure a layout of PEX pipe (polyethylene cross-linked tubing) to a wooden sub-floor or foamboard base.

The stapler head holds the PEX in place as staples are fed, via a non-stick polymer slide, to the plunger assembly.

The durable, lightweight magazine slide is made of a solid, one-piece engineered-polymer which balances the tool by directing the weight over the stapler head.

Loading strips of 25 staples are joined together flush with a clean plastic weld to further enhance smooth stapling action.

Exclusive Staple Designs

Exclusive Malco plastic staple designs easily secure layouts of 3/8, 1/2 or 5/8-in. (9.5, 2.7 or 15.1 mm) PEX.

The PEX to Wood Staple No. PWS2 features two .083 x 3/4-in. ring-shank stainless steel nails for superior pull strength in a wooden sub-floor.

Foamboard Staples feature dual barbs for increased bite and superior holding power.  Additional barbs on the 2-1/2-in (63.5 mm) staple double the holding power in 2-in (50.8 mm) foamboard.

Specify Malco No. FBSN1, 1-1/2-in. Staples for 1-in. foamboard.
Specify Malco No. FBSN2, 2 -1/2-in. Staples for 2-in. foamboard.
