• High-quality injection molded side plates with through-bolted and riveted construction
• All load-carrying components manufactured from 316-grade stainless steel for corrosion resistance
• Stand-up block design ideal for use on larger cruising and racing yachts
• Safe working load of 2,750 lbs (1,250 kg) with break load of 5,500 lbs (2,500 kg)

Specifications:

• Overall Length: 6-3/8 inches (162 mm)
• Sheave Size: 2-3/4 inches x 3/4 inch (70 mm x 20 mm)
• Maximum Rope Diameter: 9/16 inch (14 mm)
• Weight: 444 grams
• Safe Working Load (SWL): 2,750 lbs (1,250 kg)
