![ronstan-1500x1500](https://www.rhsboating.com.au/images/com_hikashop/upload/ronstan-1500x1500.jpg)  Description:
Find useful fittings for everyday boat maintenance with selected Ronstan marine hardware from RHS Boating & Marine. Our range includes cam cleats, clam cleats, drain plugs, housings and replacement washers, bringing together components for line handling and drain-plug servicing.

For cleats, match the stated rope diameter range and mounting dimensions to your intended installation. For drain plugs, check thread type, housing compatibility and seal condition; fine and coarse threads are not interchangeable. Individual parts and multi-piece packs may also differ in what they include. Browse by application and compare the product details to select the correct Ronstan fitting for your repair, replacement or boat improvement project.
