The Barton Size 5 54mm plain bearing pulley block with single swivel and becket provides verified load capacity and corrosion-resistant construction for larger cruising and racing yachts.

If your rig requires a compact block that handles heavier control lines without premature wear or corrosion, this product addresses that need. Load-carrying parts and the interior frame are marine-grade 316 stainless steel and the moulded side plates are through-bolted and riveted for structural security under load.

• 54mm x 17mm plain sheave suitable for up to 12mm (7/16") rope
• Safe Working Load 750kg and break load 1500kg for measurable strength
• Marine-grade 316 stainless load-bearing components for saltwater resistance
• Through-bolted and riveted moulded side plates for added structural security
• Single swivel with fixed becket for secure attachment and articulation
• Compact weight 220 g and dimensions 150 x 58 x 37 mm for easy mounting

Use this block for mainsheet travellers, halyards, reefing lines or other control systems where a 54mm sheave and a becket option are required. Compared to smaller blocks this Size 5 accepts larger rope and higher working loads. It is compatible with Barton ball bearing mainsheet traveller systems though this unit uses a plain bearing sheave.
