Sargent 815 LHR BLACK – Frequently Asked Questions

1) Which Sargent exit devices does the 815 LHR open back strike work with?
The Sargent 815 LHR open back strike is built for Sargent 7300, 8900 and 9900 Series exit devices set up left hand reverse. It is the frame-side half of the latching system on those devices. If your device is from a different Sargent family, or a different brand, this is not the strike for it.
2) What does LHR mean on a Sargent 815 strike, and how do I know that's the hand I need?
LHR is left hand reverse: standing outside the opening, the hinges are on your left and the door swings toward you. Strikes are handed, so an LHR part will not serve a right hand reverse opening. Check the hand of the door before ordering the 815 LHR, because the open back pocket has to face the direction the latch comes in from.
3) I just need to fix a Sargent exit device that won't latch. Do I buy a whole new device or just the strike?
If the device itself operates and only the latching at the frame has gone bad, the strike is the part to replace. The Sargent 815 LHR is a direct replacement strike for existing 815 LHR installations, so the device, rails and trim stay on the door and you swap the frame-side component only.
4) What is an open back strike on an exit device, and when do you need one?
An open back strike has one side of the strike pocket left open rather than fully boxed, so the latch can pass laterally instead of only straight in. That is what lets it work in door and frame conditions where a closed box strike would bind. The Sargent 815 is that style, and it is the strike used on Sargent 7300, 8900 and 9900 Series devices in the LHR hand.
5) Can I use the 815 LHR strike on the other doors in my building to standardize?
Only where the device family and the hand both match. Any opening running a Sargent 7300, 8900 or 9900 Series device in the left hand reverse configuration takes the same 815 LHR strike. Openings with the opposite hand need the opposite-hand strike, so a mixed-hand building will carry two part numbers, not one.
6) Is the Sargent 815 LHR strike rated for commercial traffic or is it a residential part?
Strictly commercial. Sargent lists the 815 LHR as a commercial door hardware component, and it is used on openings in offices, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings.
7) What finish does the Sargent 815 open back strike come in?
Black, and it ships as a single standard finish option, so there is no finish to select at order time. The black is meant to sit alongside the matching Sargent exit device trim on the opening.
