B-Line Eaton series runway support, Used to support cable runway from objects, Includes 5⁄16 J bolts and nuts, Runway support, ASTM A36 structural ste

It supports cable runway from an existing object overhead or alongside, rather than sitting on the floor. Eaton B-Line model SB2261804YZ is a runway support bracket in yellow zinc ASTM A36 structural steel, and it ships with 5/16 J bolts and nuts so you can clamp it to the supporting member without adding separate fasteners.

No. The 5/16 J bolts and nuts come with the support, so the mounting hardware for attaching it to the object is in the box. You still supply whatever hardware your runway manufacturer calls for at the runway-to-bracket connection.

The support measures 21.75 in length/depth, 18 in width, and 4 in height, and weighs 2.4 lb. Lay those out against your available space above the runway before you set your hanger points, since the 4 in height is what determines how much vertical room the bracket itself eats up.

Yellow zinc over ASTM A36 structural steel is a plated indoor finish. It is the right pick for equipment rooms, data centers and telecom closets. For exposed exterior runs or wet areas, specify a hot dip galvanized or stainless support instead, because plated zinc will not hold up to sustained weather exposure.

A36 is standard structural carbon steel, the same grade used for building framing members, so it is a structural bracket and not sheet stock. The support is built from yellow zinc ASTM A36 steel. Load capacity on a runway still depends on your span, spacing between supports and the runway itself, so size spacing to the runway manufacturer's load table.

Order it by Eaton B-Line model SB2261804YZ. That single model number covers the yellow zinc runway support with the 5/16 J bolts and nuts included, so there is no finish or size suffix to pick.
