el="nofollow" href=http://www.hammondmfg.com/1553T.htm target=blank>1553T versions without a##IMAGE_1_R## battery box have two removable end panels; the battery versions have a single panel at the top of the unit. The battery box in the larger unit accepts 4 x AA or 2 x 9V cuboid batteries, 2 x AA or 1 x 9V in the smaller; connectors for both types are supplied. The removable plastic end panels are easily machined to provide cutouts to suit LEDs, connectors and switches as required.

Moulded in flame retardant ABS, the units have a smooth curved shape that fits comfortably into the hand. They are produced in light grey or black, both with over-moulded contrasting soft side grips as standard. Both top and base are provided with PCB mounting standoffs and the two shells are assembled together with screws into brass inserts, allowing repeated access to the interior without degrading the closure.

All units can be supplied factory modified with machining and silk screening to the user’s specification.
