Nelson Fastener Systems Strand Support Stud R5P

Nelson R5P studs are welded to plates that are cast into prestressed concrete beams and structural members for building construction. The studs are positioned so that a prestressed cable strand bears on the notch in the end of the stud. The strand pressure applied to the stud and plate assembly keeps the plate securely in place against the form while the concrete is poured and has cured. The bottom of the notch, which determines the height of the strand, can be calculated by subtracting the 3/4” notch depth and the 1/8” weld burn-off, from the overall length of the R5P stud. Older R8P style strand supports only had a “V” notch in the top of the stud, and proved to be not as reliable as the R5P studs, which have a crimpable deep notch. D2L or H4L studs are often welded to the same plates as the R5P studs.
