Creates an incredibly strong corner structure by utilizing metal-wood-metal sandwich construction. Bolt holes line up perfectly when teamed with any Kwikdox Interior Corner plus double 2x wood joists (or any framing material that adds up to about 3" total thickness). The holes in Kwikdox interior corners as well as this mating outside corner are oblong to allow for some variation in framing thickness or installation misalignment.
Holes sized for 3/8" fasteners. Manufactured in Canada from North American Steel.
