The Davis Instruments FenderFriend Center Tube (Black) is a smart, all-in-one solution designed to keep boat fenders securely positioned while reducing strain on your hardware. Featuring a built-in Shockles® shock absorber, it stretches to absorb impact when fenders are compressed between the hull and dock or during wakes and surges, helping protect rails, cleats, and stanchions from stress or bending. The UV-resistant adjustable strap fits a wide range of setups—from 16 to 72 inches—while a durable marine-grade nylon buckle allows for quick attachment and easy height adjustment without complicated knots. Purpose-built for center-tube style fenders, it provides reliable positioning and added peace of mind whether docking or leaving your vessel unattended.
