Product Overview
The Buyers PH50 is a 50-ton air-compensated pintle hook built for high-capacity towing applications. Constructed from austempered ductile iron and finished in a durable black powder coat, it’s rated for 100,000 lb gross trailer weight (GTW) and 20,000 lb maximum vertical load (MVL).
The PH50 mounts on a 6-hole bolt pattern using ¾-inch Grade 8 bolts (sold separately). Bolt spacing is 5.00" horizontally and 2.125"/2.375" vertically, with 0.781" clearance holes for proper fit. Buyers recommends torqueing each fastener to 475–500 ft-lb.
This pintle hook can be operated with or without an air chamber and plunger. When used with the optional PH50ACMK air kit, the system provides smoother, cushioned engagement. Without air, it functions as a standard mechanical hook — ideal for simpler fleet setups or retrofit applications.
This listing includes the pintle hook only. Mounting hardware and air kits are sold separately.
