Mini snatch block are a very light solution, completely made in U-V resistant high strength resin. They can be fastened both with a line or with a shackle.
OPF series – new by Antal, the “One Piece Frame” block without pins or screws, is a light and strong solution.
Looper series are ultralight OPF blocks provided with a dyneema Snap-Loop for fast, easy and safe connections.
Mainsail systems available in two sizes:
XXL blocks – the nuts and bolts have been replaced with recessed screws and pins, considerably reducing weight and eliminating any projecting parts. The main bearing is made of high-strength composite fibre impregnated with self-lubricating substances.
Classic series with a traditional design, is conceived especially for classic boats.
S.steel mini blocks offer extremely high working loads (34x6 block = 400 kg, 40x8 block = 500 kg) while still compact and lightweight.
Halyard blocks, designed for halyards at the base of the mast, keep the line as close to the deck as possible.
Hollow pin deck block / opf hollow pin – the sheave rotates on a hollow pin with the line passing through the pin’s centre. This type of arrangement reduces the height of the line off the deck, and the side loads on the block.
Mast blocks – hard black anodized aluminium frame with insulating washers for corrosion protection.
Organizers – groups of 2 to 6 sheaves in 3 diameters of 40, 50 and 60 mm.
Tulip series – sheaves have a particular groove shape that allows a line lead angle range of 40°.
DYNABLOCK – the new Antal block with revolving resin cheekplates and with a Dyneema snap loop protected by a polyester cover.
Snatch blocks – the cheekplate revolves around the sheave axle allowing the block to open. A safety pin, which engages automatically on closing, stops the block from opening accidentally.
Snatch looper, a block with a small sheave and a Dyneema snap loop suitable for high loads, particularly designed for 2:1 main halyards.
Low friction rings are simple, lightweight, resistant and require no maintenance. Thanks to the perfect polishing, they give extremely low friction.
16 mm block is Harken’s smallest block. It is perfect for small synthetic control lines found on high-tech dinghies and has a 113 kg (250 lb) maximum working load.
Micro blocks are low-friction, compact and lightweight. They are ideal for sailboards, smaller dinghies, and lightly loaded control lines on boats of all sizes.
T2 soft-attach carbo blocks are high-strength, soft-attach blocks in 18 to 57 mm sizes. They have no metal shackles or rivets, making them the lightest soft-attach blocks Harken has ever designed. All T2 blocks are lashed or spliced through the load-bearing centre of the block, decreasing the loads on the sideplates and acting as a safety backup for the system.
T2 soft-attach ratchamatic carbo block s Harken’s newest block to feature the T2 line’s styling and soft-attachment system with a minimum of moving parts in the ratcheting mechanism. Pressure on the line engages the ratchet mechanism, which switches seamlessly from free-running to ratchet mode. Unloaded main and jib sheets run out freely.
Wire high-strength blocks carry wire halyards and high-strength control lines on boats of all sizes.
Hexaratchet midrange classic blocks grip loaded sheets, yet allow sailors to ease and trim quickly and with complete control. A switch on the side engages and disengages the ratchet mechanism.
Black magic air blocks are strong and lightweight with a high strength-to-weight ratio. Air blocks are easy to clean and service. They have few parts and no loose balls or rollers to misplace. Unlike blocks that are riveted, fasteners allow quick disassembly with a single hex wrench.
Cruising esp blocks are simpler in design and construction. Available in aluminium or hand-polished stainless steel.
Megayacht blocks the clean, crisp look of aluminium is perfect for performance-oriented yachts. Can handle extremely high loads.
Stainless steel blocks reflect the traditional beauty of your yacht’s classic lines. Stainless sideplates are mirror-polished for durability and unmatched esthetics. Can handle extremely high loads.
TTR2 air blocks are lightweight and strong. Titanium rollers handle bearing loads, while high-wear composite thrust bearings handle sideloads for reduced maintenance. The loop is lashed tightly through the block’s lashing window or through the block’s hub. This increases block stability and keeps it from capsizing.
Classic wooden blocks combine the warm appeal of old-world craftsmanship with durable, low-friction, high-strength Harken ULC bearing systems. Block shells are crafted from hand-selected, classic maritime elm which resists splitting and does not dry out. A gloss finish protects the wood from the elements and gives it a deep, rich shine. Sheaves are constructed of high-strength, corrosion-resistant, black-anodized aluminum or a rich finished bronze—perfect for today’s high-strength rope and winches.
Footblocks are used to redirect lines on the deck. Foot blocks with Lockoffs temporarily secure sheets.
Mastbase halyard lead blocks can be grouped in a small area at the mast base. Also available in teardrop or over-the-top version.
Runners are used on running backstays. AIR RUNNER® BLOCK SOCKS - foam padded Block Socks easily install over Air Runner blocks to protect your blocks, deck, and crew.
Flip-flop blocks are low-profile, lightweight and can be used for various leads. Keeps the line close to the deck. Hinged construction allows variable leads. Lockoff provides a temporary stop to free up winches.
Through-deck blocks are used to lead control lines through the deck and bulkhead of offshore boats.
Snatch blocks are offered in standard and high-load configurations and are used on offshore boats of all sizes. STANDARD blocks feature low-friction roller/ball bearing sheaves and a unique push-button latch for one-handed operation. The opening side allows sheets to be inserted without reeving. HIGH-LOAD blocks can quickly be fastened wherever needed. ULC bearing technology ensures sheaves turn smoothly and maintain efficiency at high loads. The articulating LOUP® soft attachment carries the block’s primary load. Strong, lightweight Velcro® strap holds block closed when sideplates are aligned.
Deck organizers lead multiple lines aft to halyard stoppers or winches.
Control blocks are ideal for use with hand-held loads. They feature lightweight, performance load-bearing capacity, as well as exceptional strength and durability. The open design allows sand and salt to be flushed out easily, keeping maintenance simple.
Synchro blocks reduce friction and increase efficiency by up to 40% over budget blocks on mainsheet systems. Easier, smoother transfer of power from deck to sail and less wear on your rope. Simple switch to change from swivelling to fixed shackle. Head can be positioned for use in line or at 90 degrees – or left to rotate freely when in unlocked position. When locked allows 30° “float” on shackle post to improve alignment of block.
Htx blocks are constructed simply from high quality materials, providing enhanced reliability. Ideal for frequently adjusted, highly loaded systems using modern line technology and reduced line diameters. HTX blocks are more efficient than alternative brand using similar material due to machined bearing pin surface. HTX block efficiency improves above 450 kg as acetal sheaves become self-lubricating at this point.
Racing blocks Manufactured from the best materials, they offer incredible strength to weight ratios. Lockable head pin, highly efficient central bearing, Delrin thrust balls, ratchet fiddle blocks feature alloy ratchet sheaves and recessed ratchet lever.
