Top Rail Section
Also known as
Handrail Section, Top Rail, Guardrail Rail, Aluminum Top Rail, Railing Tube
Used for
Spanning between guardrail stanchions to form the primary handhold of a deck guardrail system. The rail seats into the stanchion cup at each end and is secured by a spring pin or set-screw. OSHA 1910.29 requires the top rail height to be 42" (±3") above the walking surface for general industry applications.
Trade note
Top rails are typically aluminum tube (1-1/2" or 1-5/8" OD) supplied in standard section lengths — 4 ft, 6 ft, and 8 ft are most common — that match the stanchion spacing of the staging system. Aluminum rail looks similar to the tube stock used in electrical conduit; the difference is the factory-drilled pin holes at each end. On load-out, bundle rail sections by length and label them: mixed lengths add up to a headache at the next venue.
