Product overview

• Slotted sections inside to accept PCBs with numerous mounting pillars for fixing boards in place• Top and bottom sections are held together by two screws• It is possible to have a combination of vertical and horizontally mounted boards

This large box is supplied in light grey and includes black front and back panels. The large box has ventilation slots along the edges of the top and bottom sections - the bottom section also has a circular slotted area that would be suitable for a small loudspeaker.

Rated 5 out of 5 by from looks proffesional and works I housed a server psu in one of these and put a volt and amp meter and multiple outputs . The case helped it look great. There are nipples iside to accept screws and also slots for boards . These enclosures help you make stuff fit . The loudspeaker vents as its descibed , i fitted a small fan to circulate the air around the psu . A very good box that will give your prject a proffesional look .

Rated 5 out of 5 by from Useful project box I used one of these boxes to house a hifi amplifier that I was building. It was very convenenient to use - in particular the was that the front and back panels fit into the grooves in the lid and base. Highly recommended!

Hi, Did you get a drawing for this box? I have just bought one and need to have holes machined in it to house controls etc and to mount the equipment inside. I can't give those details to the engineer without the drawing.

Do you have a technical drawing for this case, or a data sheet? I would like to check some of the internal dimensions such as screw centres and front panel size.
Asked by: Ben Cook
We don't have a technical drawing for this product at this time. I will contact the supplier and request one. I will email you a copy once I have one.
