Nelson Fastener Systems Rectangular Notched Stud R2P

Nelson R2P studs are sued in a variety of ways to secure one and two component refractory linings. The refractory may be low density blanket or block, or medium to high density cast, gunned, or troweled insulation. When used with a single component cast, gunned, or troweled lining, the R2P is welded, the tines spread, and the refractory placed. With two component linings, the R2P is welded, the back-up layer placed, the tines bent, and the working lining placed over the bent tines. We suggest that the tines be spread to a maximum central angle of 70°. Spreading the tines may be easily done with a piece of small diameter pipe or a set of pliers. The Nelson R2P is also used to secure block insulation alone. In this case, the stud is welded in place, the insulation impaled over the stud, and the tines bent flush with the insulation. The 1/8 x 3/8 R2P is most frequently used for this service, with the length chosen so that the tines protrude at least 1-1/2” beyond the impaled insulation before bending.
