Access Doors & Inspection Hatches
Hinged and lift-off access doors with gaskets, locks and stays.
Access doors that seal when closed and stay open when opened, because an inspection hatch that swings shut on your arm gets propped with whatever is nearby.

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 1.0–3.0 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, Aluminium 5052-H32, rates 7/10 on our machinability scale at 60 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 5 pieces, so on a first order setup and programming are spread over very few parts and they are most of the price. Repeat orders at the same quantity are cheaper without anything on the drawing changing.
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 fit a stay to a small door?
- Because it is the ones you expect to hold open that damage fingers. Any door heavier than about 2 kg gets a stay, or a hinge that will hold it by friction.
