The 550ALR is equipped with the PrimSurfer roller base. The PrimSurfer fulfills the need for increased speed and precision in large surface as well as residential flooring jobs. Its two-way fluid sideshift extends the natural hand movement and matches the agility of the installer, allowing a constant, comfortable posture that prevents “top nailing”. Not having to lift the tool repeatedly eases off the feeling of tension in the users arm and back. PrimSurfer also provides a substantial gain in time and installed surface, which translates into more benefits for the contractor. First to develop and perfect this groundbreaking addition, Primatech keeps improving it with a new generation composite and lighter carrier frame for its adjustable EXPERT series flooring tools.

Main features of the 550ALR Version:

The 550ALR version features a fully adjustable baseplate providing 3 distinctive advantages:

Other features:

• Can be actuated from any angle
• Light mallet impact will set nail perfectly
• No recoil
• Simplified maintenance
• 3/8″ to 3/4″ (10 to 19 mm) flooring
• No shims required : the built-in adjuster eliminates the use of shims to match the board thickness
