The Key-2030 has two ace cylinder locks that are keyed separately. The top lock gives access to the box itself, while the bottom lock gives momentary contact to open or close the gate (the key is removable in the closed position only). Construction and mounting features are the same as the Model-2030 and two keys are also supplied for each lock. Dimensions: 5 1/2″ (H) x 4 1/2″ (W) x 4″ (D). Note: Because the weight of this item is over 1 LB, a $5.00 handling fee will be added to the price of the item.
