Vertical Railings Hardware and Swaging Stud
Vertical Railing Boring Diagrams
Top Rail Holes on the underside (only) of the top rail are drilled and taped on 3.25" centers to accept Invisiware® 5/16-24 Threaded Studs for 1/8" or 3/16" diameter cable. (Note that every eighth cable is replaced with a rail brace, to keep the top and bottom rails from bending).  
Bottom Rail Holes are drilled 3.25" centers to accept Invisiware® receivers for 1/8" or 3/16" diameter cable. (Note that every eighth cable is replaced with a rail brace, to keep the top and bottom rails from bending).
Vertical Railings Other Construction Notes
Railing MaterialUse minimum schedule 80 steel or stainless steel pipe, or square or rectanggular tubing with a minimum 1/4" wall thickness. For exterior applications, specify stainless steel to prevent problem with rust in the frame.
Rail Braces
Rail Braces should be used in the place of a cable at least every eighth cable to support the top and bottom rails under tension. Specify .625" diameter x .120" wall thickness type 4130 Chrom./Moly tubing or .625" diameter x .120" wall thickness seamless stainless steel tubing.
The factory can supply the following vertical railing components:
Top and bottom rails ready to accept hardware in sections up to 20 feet in 1-1/4", 1-1/2" and 2" standard schedule 80 pipe and 2" x 2" x .250" steel tubing. Material is mill finish carbon steel or stainess. We can also drill and tap or counterbore customer's material as required
Rail Braces to the above specifications, coped to fit into pre-drilled top and bottom rail holes, where they can be welded into the frame.
Cables cut to specified length with Invisiware® Threaded Studs swaged on both ends, ready for fast field installation. |
