The Kindorf system is designed so that most accessories are compatible with 1-5/8 in. strut. Conduit and pipe straps will work equally well with 1-5/8 in. and 1-1/2 in. strut.
Designed so that the maximum number of support and framing applications can be constructed with a minimum amount of labor and pieces.The 1-1/2 in. dimension in the channel, hole spacing and fittings means all parts fit together, no matter where they are used, or at what angle.
