Black Magic® AirBlocks® offer Grand Prix technology to all racers. Lightweight sculpted aluminum sideplates, low-friction Torlon® rollers and captive ball bearings. Loops, singles, doubles, fiddles and standups.

Cruising ESP Blocks change the direction of statically-loaded line. Axle bearings handle high static loads, contained ball bearings side loads. In aluminum and stainless steel.

Snatch blocks have opening sideplates to allow sheet insertion without reeving. Easy to open with the one-handed push-button latch. High and low load configurations.

The Carbo Ratchamatic® rolls freely under low loads; automatically engages the ratchet mechanism for high-load holding power. Adjustable ratchet engagement levels.

Lightweight Carbo AirBlocks® are strong with high working loads. Sheave runs exclusively on ball bearings for fast trim under any load. Patented switch locks shackle in three positions.

BLOCKS: Simple and efficient, the KBO Block is outstanding for numerous applications. Attached with a rope shackle, it is simpler to use than a regular D-Shackle block. Efficient design and high quality materials make the KBO unequaled in weight to working load ratio.

Automatic ratchet block. Sheave automatically changes from free-turning to ratchet when the load increases. The switch-over point is set using an Allen key. Control and Convenience.

Ball bearing blocks (BBB). Stainless steel ball bearings. Unique Acetal bearing cage decreases friction from ball-to-ball contact and reduces weight. 20, 30 and 40 mm sheave diameter.

High load plain bearing blocks. Optimised for wire applications exposed to rig loads such as backstay bridles. Stainless steel, electro polished cheeks, hard anodized aluminum sheave. 60, 80 and 100 mm sheave diameter.

Plain bearing blocks (PBB). Designed for low friction under high static loads. Tool-free switch from swivelling to fixed shackle. Torsionally rigid composite cheeks with internal stainless steel strap. 50, 60 and 80 mm sheave diameter.

ROLLER BEARING BLOCKS
Low resistance at high, dynamic loads makes for fast, safe and uncomplicated maneuvers. Machined, black anodized sheave and cheeks. Torlon® roller bearings. Ball bearings for axial loads.
