Creating a strong connection is essential to every electrical system. By using closed end lugs you get not only durability but longevity as well. Pacer's closed end lugs are tin plated and have no exposed seams. This means that they are ideal for marine applications. What makes them ideal is the fact that they can be used to create waterproof connections. When used with epoxy heat shrink, the closed end lug will fully envelop the conductor. This leaves nothing exposed to the elements. To use, simply strip your wire or cable to the proper length. Once this is complete, slide the lug over the exposed wire making sure the insulation butts up to the edge of the lug. Now, crimp the lug using the correct tool and you're done. Add epoxy lined heat shrink for added durability. Pacer's closed end lugs are available in 8 AWG to 4/0 AWG wire sizes. The available stud sizes include; #10, 1/4", 5/16", 3/8" and 1/2".This tinned closed end lug (EDMO# TAE812R100) accepts 8 AWG wire, 1/2" studs, and comes a package of 100pc.
