I am often asked for custom sized boxes, which I cannot supply because I do not make these boxes.

However I have recently been offered custom milled aluminium enclosures, This is a trial run so I cannot estimate the prices
The parameters required will be the inside dimensions  ( pcb size in metric ) Because the milled area will
need to have radiused corners, the milled space will be larger than the PCB which we expect will be 
mounted on pillars or screws to the bottom of the enclosure. The other parameter required is the number
 of lid bolts. Four is possible but not recommended for microwaves as the lid will tend to bow and probably
 leak. Six or more is better but will require thicker walls. 

Please enquire with your requirements via my email address above

Recent queries about internal dimensions for sizing the pcbs suggest that you should subtract about 2mm from the quoted external dimensions

Please note I do not make these boxes they are imported from Germany to the UK and a custom box size requires a minimum order quantity of 20 units, so this is generally not economical, unless you are marketing a project.

Eurocard sized
1000111  162 x 102 x 30mm.......................£8.00ea.
1000161  162 x 102 x 50mm.......................£8.50ea.   currently out of stock

Other sizes can be ordered to suit your requirements, please ask. Please note it is easy to make boxes of a different, shorter, length from these by pruning the long side wall. You are of course left with a "too long" lid but at least you have only one flange to fold to alter that, after cutting the lid down. If fact, reforming the lid flange is not actually necessary and the cropped lid can be secured with a couple of dabs of solder.....not as pretty though....I am sure our German friends would not approve !

Other sizes not stocked.....at present ...Please ask I can add your requirements to my next order

Masthead mounting enclosures (Schubert) 
I am stocking two sizes of the Schubert Masthead enclosures, the Medium and Large
These consist of a plastic "Hood" and "L" shaped base-plate drilled for a mast clamp
self-tap screws, and a mast clamp Medium pictured  below

Medium size Masthead assembly...............................................................£22.00ea.
Large size Masthead assembly...................................................................£35.00ea

Note that these can be supplied without the 60mm  mast clamp for £15 and £28 respectively

Filter boxes   (Popular for G4DDK wideband pre-amps)

Filter boxes (Tin-plate). These come in two sizes, they have the same width and height (20mm square) but are available 37mm and 55mm lengths. They are pre-punched at both ends to take BNC connectors (with the alignment "flat") and can be supplied as a kit with either grounded or isolated BNC sockets (ask)
They are ideal for isolating transformers and small in-line filters or attenuators, or even couplers !! These are suggested for use with the wideband amp pcb kits that Sam G4DDK sells. 
Schubert has increased his prices for these.


FG2P 20 x 20 x 55 (punched BNC)........................£3.10ea
FG1P 20 x 20 x 37 punched BNC .........................£2.40ea  There is not much room left if you insert a single hole BNC, but are useful with Phono or coaxial Power sockets. 
For those who want a different connector I also have un-punched boxes now in both sizes in stock
FG1  20 x 20 x 37 (un-punched)........................£2.40 ea. 
FG2  20 x 20 x 55 (un-punched)........................£3.00 ea.
FG3P 20 x 20 x 74mm (punched for BNC).........£3.10 ea. (Much more room to mount components between the BNC spigots.)
