    ### 4” Aluminium Bow Roller

This 4-inch bow roller uses aluminium and plastic components, with a black poly roller. Its 100 × 50 mm nominal mounting area provides a defined footprint to compare with the available space at the bow.

The internal width and vertical opening at the pin are different measurements and should both be checked against the intended anchor, rope or chain arrangement. A nominal mounting area describes the footprint; it is not a drill-hole spacing specification. Extra-wide and extra-high versions have different clearances, so use the figures for this code.

Replacement roller and pin-kit numbers below help identify service parts. A listed replacement or bolt-kit number identifies a compatible part and does not mean that a separate spare kit is included. Match the full assembly before ordering parts, especially where a nose roller differs from the main bow roller.

### Choosing and using this product

Plan how the equipment will be reached, deployed and secured when not in use. Keep the connections accessible for inspection and follow the relevant anchoring-equipment instructions. A storage position should accommodate the complete assembly without trapping the rope beneath other gear.

After use, inspect the anchor and connecting components together. Look for wear or damage at the attachment points and keep the selected sizes with the boat’s equipment records. This makes it easier to replace a worn component while maintaining the intended arrangement.

For a bow fitting or anchor accessory, check the actual anchor and mounting arrangement rather than relying on the name of the style alone. Clearance, pin size and the way the parts sit together can affect whether the selected version is appropriate.

If the listing is a kit, compare every stated component and length with your requirement. Rope, chain and shackles can differ between packages that use a similar anchor. Accessories mentioned as matching parts should be treated separately unless they are expressly included.
