The Maypole MP450 Keel Block is a durable, non-marking polyurethane block designed to support and protect your boat’s keel during launch and recovery. Measuring 160 × 47 × 46 mm and fitted with two M10 plated studs, it provides long-lasting, reliable hull support for most boat trailers.

Product Description:

The Maypole MP450 Keel Block is specifically engineered to offer robust and non-marking support for your boat’s keel, ensuring safe launching and recovery every time. Manufactured from high-quality polyurethane, this keel block provides exceptional durability and resistance to wear, oil, and salt water — making it ideal for use in marine environments.

Unlike traditional rubber blocks, the MP450 will not leave black marks on your boat’s hull, preserving its appearance while delivering superior support. The material’s resilience also ensures excellent shock absorption to protect the keel and hull from impact or abrasion when loading and unloading your boat.

Featuring two moulded-in M10 plated studs, the block is easy to install securely on trailer frames and compatible with a wide range of brackets and fittings. Its compact dimensions — 160 mm width, 47 mm height, and 46 mm depth — make it a versatile option for most trailer setups. Weighing just 390 g, it offers strong performance without adding unnecessary bulk.

This keel block is part of Maypole’s renowned range of non-marking boat rollers and support blocks, trusted by boaters for their long-lasting performance and minimal maintenance requirements. Whether you’re replacing a worn component or upgrading your trailer, the MP450 delivers reliable, hull-friendly support for years of use.
