This holster is for the Motorola 3000 & 5000 radios. The radio fit is very secure with three retention adjustment screws and with the deepness of the holster body there is no need for a retention strap. The transmit button is covered to prevent accidental activation. If the operator would prefer to have access to the transmit button, there is no extra charge. Please make this request on the checkout page under Order Notes. There are two ride height choices, high or low. Judge from the picture the one that works best for your need. This package is ideal when used with speaker mic’s and ear pieces. Tighten down the tension screws appropriately and be assured your radio will not come loose.
