Heavy-Duty Battery Securing Block Kit

Secure your battery properly — no movement, no flex, no corrosion. This heavy-duty battery block kit is engineered for harsh marine, off-road and outdoor environments where vibration, UV exposure and weather destroy standard mounts. Manufactured from specialty high-performance polymer with high UV stability and impact resistance, the blocks maintain strength without cracking or becoming brittle over time. Supplied with stainless steel hardware, the system delivers long-term durability and a clean, secure installation across a wide range of setups.

The universal layout suits virtually any battery size (minimum footprint 250mm x 100mm), with larger batteries easily accommodated. Includes 4 corner battery blocks, 2 tie-down mounting bars with stainless tie-down points, stainless screws and hardware, plus a heavy-duty tie-down strap. Mounting screws are intentionally 10mm longer than the block height to allow proper penetration into your chosen substrate for a secure anchor. Ideal for boats, 4WD dual battery systems, caravans, campers, off-grid power systems and custom battery installs. Not designed for under-bonnet applications.
