Primatech 550ALR 18GA Pneumatic Nailer w/Roller Base

SKU: 550ALR.

Reg: $699 / box/unit

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 user’s 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:

  • Assembled with A866 PrimeSurfer roller base
  • Short nose and compact valve design provide an all around striking surface, enabling the nailing of more boards closer to the end walls.
  • No shims required. The built-in adjuster eliminates the use of shims to match the board thickness.

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

  • High speed action and minimal moving parts result in a powerful yet soft stroke, a shorter air-saving cycle and increased precision.
