Clamshell - the Latching Drawer Front
Drawer front with a locking paddle latch, powdercoated steel, keyed alike. Secured to the drawer front via one-way security screws. These will deter casual thieves, but if your thief has a crowbar and bloodstream full of meth he'll probably find a way in.
Can be purchased and added to a Reef at any time.
Two front options: the full face as shown in the photo, and a Sandbar-compatible front with the needed cutout. (Sandbar must be purchased separately)
