2.3
HANDRAILS AND GUARDRAILS - GENERAL
 
** NOTE TO SPECIFIER ** Check your local code for requirements relating to handrails/guardrails in general and cable railings in particular. Cable infill for guardrails is recommended to be spaced at no more than 2-1/2 inches ( 64 mm) to 3 inches (76 mm) on center. Cable assemblies require a significant amount of tension in order to minimize the deflection in the cable when a load is applied. Terminating points are very important since they ultimately support the tension cable. Terminating points for horizontal cable systems are the end posts the fittings connect to. Terminating points for vertical cable systems are the top and bottom horizontal components of the railing framework. The minimum dimensions for the terminating posts and corners of the railing framework are: Round posts, 0.145 inch (3.7 mm) minimum wall thickness; square posts 0.120 inch (3.1 mm) minimum wall thickness; angle posts 0.375 inch (9.5 mm) minimum wall thickness; flat bars or plates 0.5 inch (13 mm) minimum thick plate (Flat plate material must be doubled up and bridged by material between the Plates); 4 inches by 6 inches (102 mm by 152 mm) pressure treated wood posts.
 
A.
Design, fabricate, and test handrail/guardrail assemblies in accordance with the most stringent requirements of ASTM E 985 and applicable local code.
B.
See drawings for guardrail dimensions and configuration.
 
** NOTE TO SPECIFIER ** Delete article below if standard designed systems are not used. All systems below are stainless steel. Standard designed systems include a frame consisting of balusters and handrails and infill consisting of cables, and cable terminations. The following standard systems are based on using either 3/16 inch (5 mm) or 1/8 inch (3 mm) diameter cables.
