Model 50P FLEX Power Roller
18-Gauge Hardwood Flooring Nailer

The 50P FLEX Power Roller Pneumatic 18-Gauge L-Cleat Adjustable Hardwood and Engineered Flooring Nailer is the perfect nailer for installing vertical and horizontal bamboo, Brazilian teak, hickory, cherry and other similar wood species. This machine embodies Powernail reliability and our commitment to excellence. The urethane covered precision bearings make it ideal for use on pre-finished as well as unfinished flooring. The FLEX base easily adjusts from 3/8 in. (9.5 mm) to 3/4 in. (19 mm) without using shims or pads.
50P Series nailers use a thinner 18 Gauge cleat that is less likely to split the tongue on thinner woods. It is also recommended for flooring that is a very hard species like hickory. Many of the hard exotics available today require a thinner cleat to penetrate without splitting the tongue.
