Superior Tray offers different type of accessories, splices and connectors for proper installation of
a Cable Tray System.
HOLD DOWN CLIPS
SINGLE HOLD DOWN/EXPANSION CLIPS FOR LADDER TRAY
This clip holds flange in trays securely to a lower support channel or bracket and can also be used
as an expansion guide with a W-12 washer (sold separately) placed under the base. 1/2 inch hardware is recommended.
SINGLE HOLD DOWN CLIPS FOR HEFTY TRAY
This clip holds ladders securely to a lower support channel or bracket.
1/2 inch hardware is recommended.
SINGLE HOLD DOWN CLIPS FOR LADDER TRAY
This clip is used to hold all Ladder Tray ladders to a support channel or bracket.
DOUBLE HOLD DOWN CLIPS FOR LADDER TRAY
Double Hold Down Clips allow two side by side trays to be fastened to the support with one clip and less hardware. 1/2 inch hardware is recommended.
Note: All dimensions are in Inches.
EXPANSION GUIDES
GUIDES FOR CABLE TRAY
Expansion guides are used to secure ladder and hefty trays, while guiding the trays
when they move during thermal expansion. For expansion guide recommendations, contact the factory.
1/2 inch hardware is recommended.
HOLD DOWN/EXPANSION GUIDE FOR HEFTY TRAY
These special heavy duty tray hold down clamps and expansion guides are ideal for fastening tray
to C-Channels, such as those found on bridges. They are easy to install and reduce field labor
costs since the beam clamp set screw eliminates the need to drill the C-Channel.
GUIDES FOR DOUBLE LADDER
These expansion guides are used to retain two side by side Trays,
while allowing tray movement due to thermal expansion.
1/2 inch hardware is recommended.
HOLD DOWN CLIPS/EXPANSION GUIDES FOR CHANNEL
These clips hold 4 inch and 6 inch wide Instrument Channel to a lower support channel or bracket
and can be used as an expansion guide with a W-5 washer placed under the base.
(W-5 washers sold separately). Use 3/8 inch hardware. Nylon Pad for Hold Down Clip is available.
HANGER CLIPS
HANGER CLIP SET FOR LADDER TRAY
The two-piece Ladder hanger is used in conjunction with the 1/2 inch hanger
rod and eliminates the need for separate horizontal support members and
hold down clips of a Ladder Tray.
SINGLE HANGER CLIPS FOR HEFTY TRAY
Two inch wide single hanger clips are used with the 1/2 inch hanger rod to
hold Hefty Tray Ladder firmly in place.
DOUBLE HANGER CLIPS
Double hanger clips are used in the center of two side by side ladders and
held with a 1/2 inch hanger rod. The top bolt is included with each unit.
SPLICES AND CONNECTORS
BOX CONNECTORS FOR TRAY
Box connectors terminate Tray at switchgear housings or other metal structures.
( ) = Insert Tray Width
SINGLE CHANNEL CONNECTORS FOR TRAY
These connectors take a single channel off a Tray sideways or downward.
Hardware is included with the connector.
WALL PENETRATION SLEEVE FOR CABLE TRAY
HORIZONTAL AND VERTICAL HINGED SPLICES
Horizontal and Vertical Hinged Splices offer field flexibility to go around pipes, ducts,
and other obstacles that occur during installation. Electrical continuity is maintained
by using (AFS-C) bonding jumpers, which are purchased separately. Hinged Splices for
Tray come in sets of two. Hinged splices for Instrument Channel come as single units.
Horizontal hinged splices require field drilling of the long hinge member and all hinged
splices require additional supports, as they are not considered to be full strength
mechanical splices.
CHANNEL SPLICE PLATES
4 inch and 6 inch wide Instrument Channel systems are supplied with the following wrap
around splice plates and hardware. Additional splice plates for field cuts can be ordered
by the following catalog numbers.
STEP DOWN SPLICE PLATES
These are used to connect 6 inch tray to 4 inch tray. Hardware is included.
UNIVERSAL SPLICE CONNECTORS
These connectors are furnished with the trays. If required for field cuts, these can be purchased separately.
90° SPLICES FOR TRAY AND CHANNEL
These splices are used for field cut Tees if there is no room for bends or fittings.
They are also used for attachment to metal enclosures.
EXPANSION JOINT SPLICE PLATES
Expansion Splice Plates for tray are designed to allow 1-1/2 inch free movement between
adjacent straight lengths. When using expansion splices, it is important that the
straight run be fixed permanently to its support at the approximate center between
expansion joints whenever possible, and that all other points be supported in a
manner that the longitudinal expansion is not restricted. Supports should be
provided within one foot on each side of an expansion joint to ensure its proper
functioning.
END PLATES
Blind End Plates are available for all tray types and are furnished with mounting hardware.
( ) represents Tray Width.
CHANNEL END PLATES
Channel End Plates are similar to regular end plates mentioned above.
The part number is: ( )-EP-W-1 3/4 where ( ) represents Material Type.
Note: All dimensions are in Inches.
HARDWARE FOR SPLICE CONNECTORS
Splice hardware is offered in standard zinc plated steel finish, or in 304 and 316
stainless steel to withstand corrosive attack under many atmospheric conditions.
BONDING JUMPERS
Bonding jumpers maintain electrical continuity across hinged and expansion splices.
The aluminum jumpers are used with oxidation inhibitor under the contact points.
The short circuit rating is 2000 Amperes. Hardware is included.
Catalog Number: AFS-C
GROUNDING STRAP
Material Type: Tin Plated Braided Copper.
Length: 12 inch Standard.
Catalog Number for 600 amp rating: AFS-CT-600
Catalog Number for 1000 amp rating: AFS-CT-1000
ACCESSORIES
CONDUIT SIDE TYPE DROPOUT
This type of dropout is a bracket used to secure a conduit clamp (not included), to the
side rail of the tray, allowing cables to exit the tray into conduit drops to the equipment.
END DROPOUT
This dropout is used at the end of a cable tray system, or to provide a smooth drop
off for small cables at any point between the rungs in the ladder system. It is used
in pairs, where dropping cable from both directions, or singly, when dropping cable
in one direction.
Note: Al = Aluminum, ( ) = Insert Tray Width
MINI TRIM
Mini trim can be used as a protective edging to protect cables from sharp surfaces
that cables may contact. Mini trim is a vinyl embossed extrusion with a segmented
metal core that can be cut with a knife between the metal core segments. It will
grip edges from .010 inch to .050 inch thick, and is applied in 100 ft rolls in black.
Catalog Number: Mini Trim
GROUNDING CONNECTORS
Type GC Connectors hold a single through cable and a tap cable while separating the
ground conductor from the cable tray surface.
Note that the bolt head is mounted on the inside wall of the cable tray to avoid damage
to the cable insulation. Grounding connectors may be used with aluminum or galvanized
steel cable trays. When mounted horizontally, the bolt may be used to replace one of
the bolts in a splice plate.
GROUNDING CLAMPS
Type GBM Clamps hold a single through cable directly on the cable tray surface.
CABLE SEPARATORS
Cable separators (divider strips) are available for all tray types in aluminum, mill galvanized
and 304 or 316 stainless steel. Separators come in either 3 inch or 5 inch heights and are slotted at
regular intervals for ease of installation without field drilling. Separator Rung Fasteners
must be ordered separately for attachment to Tray rungs without drilling.
Vertical separators must be factory formed to the proper radius needed. Vertical separators
can be ordered to the degree of bend or the customer can order all 90° separators and field
cut them to the proper degree bends.
SEPARATOR FOR STRAIGHT LENGTHS
Standard length is 12 ft. The grouping of slots is designed to fit the hole-pattern of
ventilated Tray.
SEPARATOR FOR HORIZONTAL BENDS
Standard length is 6 ft. Each piece is punched and slotted for easy field adjustment to any
degree of radius curvature. Sections may be field cut or continued along a straight run.
SEPARATOR FOR VERTICAL BENDS
The following information is required while ordering:
1. Inside or outside bend
2. Degree of bend
3. Radius of bend
Example: A3V-VI45-24
( ) = Insert Fitting Suffix
SEPARATOR FASTENERS FOR TRAY
Separator fasteners allow attachment of separators to Tray rungs without drilling the rungs.
These fasteners are required 4 per straight section, 3 per horizontal fitting and 2 per
vertical fitting. Rung fasteners are stainless steel.
CABLE SEPARATOR SPLICES
