HFJD Cable Tray Coupler / Splice Plate is designed to connect adjacent cable tray or cable ladder sections and form a continuous cable support route.
The coupler is one of the key connection components in a complete cable management system. It helps align neighboring tray sections, maintain structural continuity and provide a secure mechanical connection between straight sections or transition points.
HFJD supplies different connection configurations including straight couplers, inside and outside splice plates, vertical adjustment couplers, width adjustment couplers and height adjustment couplers.
Connection plates can be manufactured according to cable tray width, side rail height, hole pattern, material thickness and project drawings.
HFJD cable tray couplers can be used with
Perforated Cable Tray Systems
Ladder Cable Tray
and other industrial cable support systems.
Cable tray couplers provide a mechanical connection between neighboring tray sections and help maintain alignment along the cable route.
HFJD can provide straight, inside, outside and adjustable connection plates according to system structure and installation requirements.
Couplers can be manufactured for perforated cable trays, cable ladders and other cable support systems.
Bolt hole dimensions and spacing can be manufactured according to the corresponding cable tray side rail or project drawing.
Connection plates can be manufactured to match the material and corrosion-protection system of the corresponding cable tray.
Matching bolts, nuts and fastening components can be supplied according to project requirements.
The outside straight coupler is installed on the outer surface of the cable tray side rail to connect two straight tray sections.
It is commonly used where external access to the connection bolts is preferred.
The inside straight coupler is installed on the inner side of the tray side rail and provides a compact connection between adjacent sections.
The final design depends on cable tray profile, side rail height and hole arrangement.
A vertical adjustment coupler can be used where two cable tray sections require controlled angular or vertical alignment.
This type of connection is useful for project-specific installation conditions where a rigid straight connection is not suitable.
Width adjustment couplers can be used in transition arrangements where the connection geometry must accommodate changes in cable tray width.
Height adjustment couplers are used where connected sections have different side rail heights or where a customized transition structure is required.
For heavy-duty cable ladder systems, reinforced splice plates can be manufactured with increased plate dimensions, thickness or bolt quantity according to project requirements.

Cable tray systems are normally installed in multiple straight sections. A coupler or splice plate is used at the joint between two neighboring sections.
The connection system normally performs several functions:
The hole pattern of a cable tray coupler should match the corresponding cable tray side rail.
HFJD can manufacture:
Customers can provide cable tray drawings or connection details to ensure dimensional compatibility.
Cable tray couplers are commonly installed using bolts and nuts.
Depending on the tray structure and project requirements, HFJD can supply:
Bolt quantity and size should be selected according to coupler dimensions, tray structure and project requirements.
Pre-galvanized connection plates can be supplied for indoor and general industrial cable tray systems where this finish meets project requirements.
Hot dip galvanized couplers can be supplied for outdoor, infrastructure and industrial environments requiring increased corrosion protection.
They can be matched with:
Hot Dip Galvanized Perforated Cable Tray
Stainless steel connection plates can be supplied for corrosive, chemical, marine and other specialized environments.
Material grades can be selected according to project requirements.
Aluminum splice plates can be manufactured for aluminum cable support systems where reduced system weight and material compatibility are required.

Perforated Cable Tray Systems
Cable ladder couplers connect the longitudinal side rails of adjacent ladder sections.
Coupler dimensions can be selected according to side rail height and thickness.
For higher mechanical requirements, reinforced splice plates with increased thickness or bolt quantity can be manufactured according to project specifications.
HFJD supports customized cable tray coupler manufacturing according to project drawings.
Customization options include:
Material Preparation → Cutting → Punching → Forming → Hole Inspection → Surface Treatment → Dimension Inspection → Matching Inspection → Packing
Inspection can include:
Cable tray couplers are generally packed together with corresponding cable tray sections or separately according to project quantity and shipment requirements.
Packing options can include:
Bolts and nuts can be packed separately and labeled according to project item numbers where required.
