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

Engineered for precision and durability, Allen Keelboat Sheet Deflectors are purpose-built fairleads designed for vessels up to 40ft/12m. Ideal wherever a shallow-angle deflection is needed for sheets or control lines, these fairleads deliver reliable performance across a wide range of sailing applications.

Key Features

Available in multiple shapes and sizes to suit virtually any deck layout or rigging configuration, Allen Keelboat Sheet Deflectors are manufactured from high marine grade 7075 aluminium — chosen for its exceptional strength-to-weight ratio and outstanding corrosion resistance in saltwater environments. Each unit is hard anodised in black for long-lasting surface protection and finished with a pad-printed Allen logo.

How to Install Your Allen Keelboat Sheet Deflector

Installing an Allen Keelboat Sheet Deflector is straightforward. Follow these steps for a secure, watertight fit:

Mark your fixing positions – Check the fixing hole centre dimensions and mark them accurately on the deck where you want the fairlead mounted.
Drill the fixing holes – Using the correct drill bit size (refer to the product drawing for specifications), drill 2 or 3 holes as required. Lightly bevel each hole to help the sealant form a solid sealing ring.
Apply marine sealant – Spread a generous bead of marine-grade sealant around the base of the fairlead and inside each fixing hole to ensure a fully weatherproof seal.
Insert the bolts – Feed bolts (not included) up through the holes from beneath the deck, adding washers to distribute load effectively.
Tighten and secure – Use the appropriate tool to tighten all bolts to a firm, even torque.

Installation Tips

Use tape to hold bolts in position under the deck while fastening from above.
Opt for 316 stainless steel hex head bolts for maximum corrosion resistance.
Use large washers to spread the load and protect the deck surface.
