### ⭐⭐⭐⭐⭐ Review
*by S***N on 1 December 2025*

Looks and works great. I was working with 6 awg wire which the crimped eyelet connector fit great. I have a ressetable 40amp breaker between this shutoff and the battery. Good smooth switch action and I like the size for my Dash Panel on a deck boat. I wish vendors would show the hole cutout. I measured 1.125 (1-1/8") diameter on the threads and 1.0625 (1-1/16") on the flats. Flats are vertical so I am going for either a simple 1.1875 (1-3/16") hole or 3d printed plate that has a 1.1875 (1-3/16") diameter hole and 1.125 (1-1/8") on the flats.
