Hello everyone, new here and I have a strange question. I have the Dewalt 0825lg Green laser that fits in a Tstak case. I have called Dewalt and the service center couldn't answer this. In the case itself it has a space for the laser, wall mount, receiver/mount, glasses/card, a space for two 12v batteries. 4 1.5 aa, 1 9 volt battery/12 volt charger. My question in the upper right corner there is a T cutout in the lower foam and a square cutout in the upper foam. What goes here? Thanks everyone for your input.
