Terminal Boxes & Junction Boxes
Small formed boxes with captive lids and cable entries, powder coated and labelled.
Terminal boxes where the lid has to close on a gasket and the cable entries line up with the gland. Captive screws mean the lid does not get lost on the floor of a plant room.

What drives the price of this part
Derived from the callouts on this page. Where a driver is not on the drawing, it is not on this list.
- Part size
- Thickness at 0.8–2.0 mm decides which machine the part lands on and how many setups it needs. Size is the driver buyers most often leave out of a first enquiry, and it is the one that changes the quote fastest.
- Material
- The first material listed, Stainless Steel 304 / 304L, rates 4/10 on our machinability scale at 201 HB. On this shop's scale a harder alloy means slower passes and more tool changes, and that is cycle time the quote has to carry.
- Order size
- Minimum order is 25 pieces, where setup and tooling are amortised across the batch and per-part cost settles around cycle time and material. Below that quantity the same part costs more per piece, not less.
See how cycle time is calculated in the machining time calculator and what else moves a price in the cost driver reference.
How these parts are inspected
Matched to the callouts above and the instruments actually on the floor.
- Coordinate measuring machine (Zeiss CONTURA G2, two machines, GR&R 8.4% on the critical feature)
- Dimensional report against the drawing, with a 100% check on critical features rather than a sample
- Certificate of conformance and the mill certificate with every shipment
The full equipment list, with counts, is on the capability page; the inspection sequence is on quality and inspection.
Questions buyers ask
- Why captive screws rather than bolts?
- Because the lid comes off in the field, and a bolt gets dropped into the grass. Captive screws stay with the lid and the box closes again.
