PART #: TP125 Description: Top Plate Adaptor for 1.25" AngleGuard on Edson Steering System W x H x D: 9.5" x 9.5" x 1.25" NavPod Protects Your Electronics In Harsh ConditionsTop Place AdaptorNavPod AngleGuards are designed to upgrade sailboat steering systems to accommodate mounting of electronics onto NavPods.Edson is a popular manufacturer of steering systems who has always used a 9.5" wide pedestal guard. Most of their pedestal guards are 1" in diameter. Lewmar (formally Whitlock) also has manufactured steering systems that use the 9.5" wide format. NavPod supplies the SG10 and AG10 as a easy retrofit onto either of these systems.Because of the clean and secure method of concealing wires and the need to accommodate large connectors and heavy radar cables within the Stainless Steel tubes, NavPod recommends the larger 1.25" diameter AngleGuards. Often the existing Top Plate needs to be bored out or replaced with the TP125 to accommodate the larger diameter. NavPod supplies Polished Stainless Steel feet with all 1.25" AngleGuards.This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.
