Junction Boxes & Terminal Enclosures
K-Display manufactures sheet-metal junction boxes and terminal enclosures around your connection layout. We coordinate the body, cable-entry pattern, internal mounting features, and cover so installation and later access fit the space available.
Make room for connections and access
A connection box needs enough room for the terminals, cable entries, and the work of making the connections. Entry placement affects routing inside the box as well as access to gland or conduit hardware outside it.
We fabricate the shell, cover, and internal mounting parts to your drawings. Terminal blocks, rails, glands, and sealing components can be identified in the bill of materials so the quoted supply is clear.
The removable cover sits above the box body. Orange marks the cable-entry locations to coordinate with the connection layout and selected entry hardware.
What we manufacture
- Box bodies
- Shallow or deep formed bodies with project-specific entry holes and mounting patterns.
- Removable or hinged covers
- Cover geometry and fastener locations matched to the available installation and service space.
- Internal mounting plates
- Plates and brackets that locate the specified terminals or rails within the box.
- External mounting features
- Tabs, brackets, and hardware provisions for the mounting surface shown in your design.
The interfaces that determine fit
- Cable-entry spacing
- Provide entry diameters and gland or fitting details. Adjacent entries need room for hardware, tools, and the specified cable routing.
- Terminal and rail arrangement
- Show component height and position, conductor approach, and clearances needed to reach terminal screws after the box is mounted.
- Cover removal
- Identify removable versus hinged access and the space available around the installed box. Fastener reach matters as much as opening size.
- Sealing surfaces and openings
- Specify the cover joint, gasket, entry accessories, and environmental requirement together. An enclosure rating depends on the completed configuration.
Build around the connection layout
Entry features and cover attachment are coordinated before finishing, so the box reaches your team ready for its agreed next assembly step.
Check entries and mounting
Review the box drawing alongside cable-entry hardware, internal components, and the mounting surface.
Form the body and cover
Produce the body, cover, and mounting parts with the specified holes, returns, and installed hardware.
Finish and supply the box
Apply the requested finish and masking; deliver loose parts or the agreed box assembly.
Leave room around the entry fittings
Two entry holes can fit on a drawing while the fittings leave too little room for a wrench. Check the full fitting bodies and the tool’s approach with the neighboring gland installed, as shown here. The wrench needs room to engage the flats and move.
Repeat that check inside the box, where locknuts compete for space with terminals and the box walls. Use the selected fitting drawings and installation instructions to establish the spacing; wall thickness and seals also affect how the threaded entry seats.
