PEX Foam Board Stapler

Malco’s FBSN Pex Foam Board Stapler is the ideal solution for installing in-floor radiant heating. A lightweight one-piece polymer magazine stands up to any rugged job-site environment. A leaf spring controlled stop automatically adjusts to setup the staples and guide it through the fastening mechanism without risk of jamming or deforming staples. Magazine loading-strips of 25 staples are joined together with a discreet plastic weld that allows staples to separate cleanly as they are engaged by the fastening mechanism.

Works great

Fast, easy, and simple to use.

Easy to correct

What a product! Made the process fast and simple. May jam or not staple if down to last few staples, but just add more sticks of staples and then there's enough weight to make it work. Easy to correct. Holds 4 sticks of staples, if I remember right.
