KEELBOAT FAIRLEAD 72x36

Allen Keelboat Fairleads | Control Line & Sheet Guides for Boats Up to 40ft

Precision-engineered for dependable on-deck performance, Allen Keelboat Fairleads are designed for sailing vessels up to 40ft/12m. Whether routing sheets, halyards or control lines, these fairleads provide smooth, low-friction guidance wherever a shallow-angle deflection is required on a keelboat deck.

Key Features

Available in an extensive range of shapes and sizes, Allen Keelboat Fairleads are versatile enough to suit virtually any deck hardware configuration or rigging layout. Each fairlead is machined from high marine grade 7075 aluminium — renowned for its superior strength, lightweight properties and exceptional resistance to saltwater corrosion. Finished with a hard black anodised coating for long-term surface protection and pad-printed with the Allen logo for easy brand identification on deck.

How to Install Your Allen Keelboat Fairlead

Fitting an Allen Keelboat Fairlead is a straightforward process. Follow these steps to achieve a secure, watertight installation:

Mark your fixing positions – Check the fixing hole centre dimensions from the product drawing and mark them accurately on the deck at your chosen mounting location.
Drill the fixing holes – Select the correct drill bit size (refer to the product drawing for exact specifications) and drill 2 or 3 holes as required. Lightly bevel each hole to help the sealant form a clean, reliable sealing ring.
Apply marine-grade sealant – Apply a generous bead of marine-grade sealant around the underside of the fairlead base and inside each fixing hole to ensure a fully weatherproof, watertight seal.
Insert the bolts – Pass the bolts (not included) up through the holes from beneath the deck. Fit washers to help distribute the load across the deck surface.
Tighten securely – Using the appropriate tool, tighten all bolts evenly to a firm, consistent torque.

Pro Installation Tips

Use masking tape to hold bolts in position under the deck while tightening from above.
Choose 316 stainless steel hex head bolts for maximum marine corrosion resistance.
Fit large washers beneath the deck to spread the load and minimise stress on the laminate.
