Wall Brackets

Superior Tray offers a variety of wall brackets to support cable trays and instrumentation channels from any wall or vertical support. The design of the brackets takes into consideration whether the support bracket will be loaded by a single cable tray run or by two runs in parallel, and if the run is horizontal or vertical, as well as the distance from the wall, the bending radii, etc.
The allowable load of each type of bracket is given for two loading conditions:
Condition 1: Where the load is applied at two points.

Condition 2: Where the load is applied as a single concentrated load at the end of the bracket.

Channel Brackets

Channel Brackets are designed to accommodate single or double channel runs with pre-drilled holes for HB-10 Hold Down Bolts. The bolts are purchased separately.
Maximum allowable load: Twice the allowable load for the respective channel at a support spacing of 10 feet.

Low Headroom Brackets

Low Headroom Brackets are used to attach ladder tray to wall mounted channel framing. These brackets are available in HDGAF.
Maximum allowable load:Condition 1: 500 lbs. Condition 2: 250 lbs.

One Piece Wall Brackets

This light duty One Piece Wall Bracket is made from 1/8" hot dip galvanized steel. Placing one bracket below another allows a minimum vertical spacing of cable trays of 8".
Maximum allowable load:Condition 1: 600 lbs. Condition 2: 300 lbs.

Medium Weight Cable Tray Brackets

Medium Weight Brackets are used to support 2 parallel runs of ladder trays side by side or one above the other.
These brackets are made of 3/16" structural angle, welded and hot dip galvanized steel.
The horizontal support angle is continuously slotted to increase the versatility of the bracket.
Maximum allowable load:Condition 1: 1200 lbs. Condition 2: 600 lbs.

Heavy Weight Wall Brackets

Heavy Weight Brackets are designed to support long spans or multiple ladder tray / trough installations that exceed the loading capacity of standard brackets. Heavy weight brakets are welded from 3" structural steel channel with 1-1/2" channel stiffeners, and is then hot dip galvanized. To maximize the loading capacity, the brackets should be installed using the 3 pre-drilled holes and 1/2" bolting hardware
Maximum allowable load:4,000 lbs. when applied as 2 equally concentrated loads, spaced at least 2'-4" apart on brackets five feet wide and under; or at least 4'-6" apart on brackets over five feet wide. The capacity is greater when used for a uniformly distributed load.

Single Strut Brackets

Constructed of HDGAF steel and designed for use with strut framing, these single strut brackets will work well in several applications. The uniform loads are shown in the table below and are represented with a safety factor of 2.5.
Allowable concentrated end load:One half the listed uniform load.

Double Strut Brackets

Double strut brackets are constructed of HDGAF steel and are used for wider cable trays and heavier loads. The uniform loads are shown in the table below and are represented with a safety factor of 2.5.
Allowable concentrated end load: One half the listed uniform load.

Strut Type Support Channel

HP-type channels provide indirect support for hanger rods by spanning between available structural support beams and channels. The channel is supplied in 10' or 20' lengths and can easily be cut-to-fit in the field. These channel lengths can also be employed as supporting members of a trapeze type support. The support channels are available in both single as well as double (back to back) configurations.
