This is a "large" Corner Gusset from GenRight Off Road. They are Laser cut from Heavy Duty 3/16" thick plate steel. They are perfect for welding into corners where you need more support. Designed with a "relief" in the gusset to go over a weld in a 90 degree corner. Two 3/8" diameter holes lasered in make a good place to hook tie downs or bungie cords.
Made in the USA!
