Shakespeare 4188-SL Stainless Steel Ratchet Rail Mount for 7/8 Inch and 1 Inch Boat Rails

The Shakespeare 4188-SL is a stainless steel ratchet rail mount built to hold a boat antenna securely while making it fast and easy to lay the antenna down and raise it again. The ratchet action gives a quick, fast-release motion so the antenna can be dropped for low bridges, storage, or transport, then returned to its correct upright position without fuss. Heavy-duty construction throughout means the mount stands up to the vibration, spray, and repeated handling that come with regular boating use.

This mount attaches easily to 7/8 inch and 1 inch vertical or horizontal boat rails, making it a practical choice for boats with standard rail sizes. A 9/32 inch hole is built in for cable feed-through, so the antenna coax can be routed cleanly through the mount rather than run externally. The mount terminates in a standard 1 inch-14 thread (male) fitting, which accepts antennas designed for that thread standard, and it is rated to handle antennas up to 8 feet in length.

Constructed of stainless steel for corrosion resistance in a marine environment, the Shakespeare 4188-SL is a durable, low-maintenance way to mount and manage a boat antenna on rail-equipped boats.
