Nelson Fastener Systems Round Corner Square Stud XBL / XXL

Nelson XBL and XXL Round Corner Square studs are a patented product developed for the installation of hanging overhead wire ways in ships. The round weld base facilitates welding in all positions, while the ¾” round corner square upper section of the stud and cross-drilled holes provide an attachment point for a variety of mounting hardware. Such hardware may be used to attach cable trays, light fixtures, ducts, and pipes. The crossbolt holes in Nelson XBL and XXL studs are accessible after 1 or 2 inches of insulation has been installed. This design permits flexibility in construction and repair scheduling, which is not possible when brackets are welded directly to the ship’s structure. The standard holes accommodate 3/8-16 bolts and are spaced 1” apart. The XBL series of studs have full diameter weld bases, while the XXL studs have reduced weld bases. The smaller ½” diameter weld bases are used for individual light fixtures and permit welding with smaller power sources. Longer round corner square studs and different hole diameters and spacing can be applied.
