This brings back that old sinking feeling that most door and hardware distributors have experienced at some point in our careers.  I haven’t worked as a distributor for more than 20 years, but I can remember the mistakes that caused the feeling.  In this case, there are 30+ door frames prepped for all-glass doors with center pivots, and an ASA strike in the standard location…one more illustration of the importance of having a knowledgeable door and hardware consultant.  This photo came from Eric Tengowski of Engineering Specialties, who was not responsible for the mismatch.

    Yes, Its a mistake but luckily in the easiest door frame material to field modify – Aluminum! All you need is an extended custom stainless trike from Accurate and in 48 hours you are out of your problem and no one will ever know.

    Extended strike will fix the strike problem 1 1/2″ or 1 5/8″ – Don-Jo can also supply them. You need to make sure you request cylindrical or one for a mortise lock.

    Yikes! It is mentioned that this door is center pivoted, but is this a double-acting application? If so, they might want a double-lip strike. Regardless, this should have been better coordinated by whoever supplied the frame and door… my guess is, this was in the glazing package. Special strikes, as noted in previous comments, will save the day.

  4. Paul Goldense says:

    Lori – if its double acting then the lock must nave a deadbolt because you can push a beveled latch right thru a double acting strike unless there is a spring loaded stop which then negates the double acting. OR is this a deadbolt only lock and the handles serve as push/pulls. Then there is likely a larger code compliance issue on egress with a deadbolt.

    My guess is that the mistake occurred in the storefront or glass entry door spec where the hardware is often specified by someone other than the hardware consultant in lieu of where it should be – in the hardware spec. My advice to all Architectural spec writers is to take the hardware out of the aluminum/glass door & frame sections and put them where they belong. Make the aluminium fabricators go to the hardware section like all the other door & frame mfrs.

    The doors and hardware were in the drywall package. In this area (Southeast), the drywall companies often provide interior aluminum frames (Raco type) in their package. In this case, they also handled the glass doors. Unfortunately, the lock was some import product that nobody was familiar with but, regardless, there is no way a standard ASA strike prep was going to work (not to mention that the locks came with 2-3/4″ T-strikes). It was wrong from every angle.
    The problem was resolved by ordering custom strikes.
    For those wondering, the lock is a dead-latch only, no deadbolt. Very simple design with a European style cylinder. The pivots are double-acting but the doors were never intended to be D.A. Stops were added to prevent the doors from swinging both directions.
