Crescent Lufkin SHOCKFORCE G2 25-Foot Auto-Lock Tape Measure

The Crescent Lufkin SHOCKFORCE G2 25-Foot Auto-Lock Tape Measure is a layout measuring instrument engineered to deliver 17 feet of standout reach across framing, carpentry, and masonry applications. Built with a 1-1/4-inch wide dual-sided blade and an automatic blade locking mechanism, this 1.21-pound layout tool holds extended lengths securely without blade creep. Featuring a diamond-coated 360-degree end hook and a bolstered drop-resistant housing, this 25-foot tape measure solves solo layout measurement and hook-slippage challenges on demanding job sites.

Best Used For:

  • Solo Residential Framing & Layout: Spanning open floor joists and wall stud lines up to 17 feet without requiring a second worker to hold the tape hook.
  • Overhead Conduit & Ceiling Grid Alignment: Reading vertical dimensions quickly on the underside scale during overhead utility and grid installations.
  • High-Elevation Structural Work: Securing the tape measure to fall protection gear via the integrated steel tether point when measuring on scaffolding or ladders.

Key Performance & Safety Features

  • 17-Foot Standout Reach: Extra-wide 1-1/4-inch blade construction enables long unsupported extensions to streamline individual layout work.
  • Auto-Lock Functionality: Automatically holds the blade extended at any distance for hands-free marking until the release lever is pressed.
  • Diamond-Coated End Hook: Delivers 360-degree grasping power on smooth or painted materials to prevent hook slippage under tension.
  • 3X Blade Protective Coating: Multi-layer barrier coating with extra Mylar reinforcement on the first 6 inches defends against blade splitting and scale wear.
  • Bolstered Impact-Resistant Case: Reinforced composite housing absorbs severe jobsite impacts to safeguard internal retraction components.
  • Dual-Sided Print Scale: Vertical reading scale printed on the underside provides clear visual alignment in cramped or overhead spaces.

What's Included

  • (1) Crescent Lufkin SHOCKFORCE G2 25-ft Auto-Lock Tape Measure
