The 1590TRPCCB is a wide trapezoid painted diecast aluminum stomp box enclosure, finished in a deep cobalt blue powder coat matched to RAL 5013. At 151 mm across its large end and 95 mm long, it is laid out wide rather than long, giving pedal builders and effects experimenters room for a row of controls or multiple footswitches on the lid.

Box and lid are diecast aluminum alloy, a tough material that is still easy to machine. The smooth glossy polyester powder coat gives a lasting finish, even after machining, and accepts labels or silk screening easily. The purchased assembly includes the box, lid and 4 cover screws that thread into 6-32 UNC holes; recommended torque is 50-55 cN.m (71-78 ozf.in), or 25-30 cN.m (36-43 ozf.in) with a gasket.

The part page lists 3.74 in x 5.95 in x 1.38 in (95 mm x 151 mm x 35 mm). The series table gives a length of 3.74 in (95 mm), width of 4.80 in (122 mm) at the small end and 5.94 in (151 mm) at the large end, and depth of 1.54 in (39 mm). The drawing shows 95.00 mm length, 121.75 mm and 151.02 mm end widths, 39.00 mm overall height, 89.30 mm inside width and 35.00 mm inside height. Maximum P.C. board dimensions are 88.3 mm and 143.32 mm. Shipping weight is 0.53 lbs (0.24 kg).

Lap joint construction protects against dust and splashing water, and the part is rated IP54. A liquid resistant version with a silicone gasket is offered separately as 1590WTRPC. The part is RoHS and REACH compliant, ships in shrink wrap, and solid models are available in STEP or IGES.
