The 12C compact strike is a versatile solution that is suitable for all types for door frames. The RCI 12C strike replaces standard, non-electrified T-strikes with a quick and easy to install electric version using minimal cutting. The compact design with dimensions of 1-13/16"W x 2-3/4"H x 1-1/8"D is ideal for wooden, steel, & aluminum door frames. Fail Secure.  1 Year limited warranty.  90 mA at 12VDC. 

If you are using this strike in continuous duty operation (electrically unlocked for long periods of time) you should also order the ICEPK, which is a voltage regulation circuit that goes into the frame and keeps heat dissipation in the strike low for long life.  When using a strike with access control, most access controls can unlock the door automatically on schedule and keep the strikes energized during the entire schedule.  This is a perfect application that would benefit from the ICEPK.
