This tiny stainless steel block is a handy component whenever you need a small but sturdy pulley. With a length of 50 mm and a slim 7 mm thickness, it can be installed in spots where space is at a premium – for example, inside a mast (for a flag halyard), on a bimini or canopy frame, or in the rigging of a small dinghy. The block is crafted entirely from stainless steel, meaning it will resist corrosion even if mounted permanently outdoors or exposed to saltwater. The narrow steel sheave works best with ropes 6–8 mm in diameter, which makes it suitable for jobs like adjusting a small boat’s outhaul, a tiller-tamer line system, or as part of a tackle for light loads.
Because of its compact size, this block is typically used where loads are not extremely high, but where reliability and smooth action still matter. It’s an excellent replacement for aging plastic blocks – upgrading strength and durability without adding bulk. For example, you might install this 50mm block at the base of a mast as a pulley for a flag halyard, or use it on a kayak sail kit to redirect control lines. The simple design allows easy attachment using a shackle or by lashing through the top eye. Despite its small size, the block is manufactured with the same quality as larger models, ensuring the sheave turns freely under tension. In sum, this compact stainless block is a versatile little helper for many scenarios – delivering marine-grade dependability in a minimalist package.
- Great For: Flag halyards, small dinghy rigging, kayak sails, or securing tarps and canopies – anywhere you need a tiny pulley solution.
- Small but Strong: Despite its miniature form, it provides a trustworthy redirect for moderate loads, outlasting typical plastic pulleys in durability.
- Easy Upgrade: Replace cheap plastic blocks on your older boat with this stainless model to increase reliability without a complicated installation or rigging change.
- Discreet Hardware: Its low profile keeps your deck or mast uncluttered – no oversized components sticking out, and minimal risk of snagging or spoiling the vessel’s aesthetics.
