Edson Pipe to Fold-Down Adapter 3-1/2" Mast

The Edson Pipe to Fold-Down Adapter 3-1/2" Mast is a specialized marine hardware component designed for vessel operators who require flexible antenna or radar mast deployment. This adapter enables 3-1/2" masts to fold down smoothly, making it essential for trailer boats, vessels navigating low bridge clearances, and seasonal storage situations where permanent mast height creates operational challenges or damage risk.

The fold-down adapter attaches to the base of your radar or communication mast using a pivot mechanism, allowing controlled lowering without disassembly. Engineered by Edson Marine, a trusted name in marine antenna systems, this 3-1/2" adapter is constructed to withstand saltwater exposure and repetitive folding cycles inherent to active boating operations. The compact design—measuring 6 x 4 x 6 inches and weighing just 1.15 lbs—ensures minimal added bulk while maintaining the structural integrity required for secure mast positioning both deployed and stowed.

Boaters with trailerable vessels, commercial fishing operations, and military or law enforcement marine units benefit most from this adapter's reliability and ease of use. Installation integrates directly with existing 3-1/2" radar or antenna masts, and the fold-down function can be engaged in seconds without tools. Compatibility with Edson's pivot hardware (such as model 992-35) ensures seamless integration into established mast systems, making this adapter an affordable upgrade for vessels requiring seasonal or frequent low-profile operation.
