Multi-level locking positions give the HD-75BXT variable-height storage capability, allowing users to position the lift where it best fits the storage setup. Spring-loaded safety locks engage continuously as the lift is raised, and the lock system can release all four independent safety locks at the same time for easier operation. Stainless and aluminum pneumatic cylinders support push-button lock release, while a secondary lock system acts as a slack-cable device for emergency protection. Combined with rugged 1-1/4-inch roller axles, anti-sway column blocks, and a durable powder coat finish, the HD-75BXT is built to keep boats high, dry, and ready for the next trip.
