• GridLoc Through Hull XL Wiring Kit is for applications where wires need to be ran through kayak or boat hulls, features a 1.5" hole designed for larger diameter components like couplers for live imagining transducers or bow-mounted trolling motors
• Backside access of install area is not required for installation, but does require a 1.5" hole - includes 12 rubber inserts with common hole sizes ranging from 0.217” to 0.550” in diameter, 4 blank inserts, 2 nylon grommets, and 2 sets of hardware
• If your install requires wires smaller than 0.217” in diameter, our standard sized GridLoc Through Hull Wiring Kit would be the better option - for a waterproof seal, marine sealant is required
• Note that this is an updated version of our original Through Hull Wiring Kit as compatibility with the GridLoc hole pattern was added to this new version, in addition we added 2 more blank inserts and 2 smaller 0.8" inserts for smaller wires
• Sold as a set of 2 - built for use in the harshest of marine conditions, made in the USA with a built for life guarantee
