Schaefer Stand-Up Swivel w/Aluminum Cheeks

The Schaefer Stand-Up Swivel with Aluminum Cheeks is a marine-grade pulley block engineered for reliability in demanding rigging applications. Built with a Delrin® sheave and reinforced aluminum construction, this stand-up swivel delivers the smooth operation and high safe working load that serious boaters and offshore anglers depend on when managing halyards, outhauls, and control lines under load.

Key specifications reflect this block's role in high-performance rigging. The 2-inch (51 mm) sheave diameter accommodates line up to 7/16 inch (11 mm), while the 1750 lbs. safe working load (790 kg) provides confidence in critical sailing maneuvers and fishing operations. Mounting is straightforward: four #10 fasteners on a 1-12/31 inch (36 mm) center-to-center spacing fit standard deck hardware. Height of 4-1/32 inches (103 mm) and overall diameter of 2-7/8 inches (73 mm) with urethane base keep the profile compact without sacrificing strength, weighing only 7.0 oz. (198 g) in aluminum construction.

Anglers preparing offshore tackle systems and weekend boaters refitting cabin cruisers or sailboats will find this block suited to mainsheet traveler setups, boom vang systems, and auxiliary control lines. The Delrin® sheave resists corrosion and salt-air degradation better than metal alternatives, extending service life in harsh marine environments. This is a genuine Schaefer Marine component (MPN 504-62), recognized throughout the boating industry for precision engineering and durability in commercial and recreational applications.
