WWYD? Doors on a Diagonal

Category: Door Closers,WWYD?Lori @ 10:08 am Comments (16)

Here’s the owner’s wish list for these auditorium doors…pull-side mounted closers, surface-mounted or easy to retrofit.  The doors are mounted on a diagonal within the opening to deflect sound.  The doors and frames are wood.  Ideas?  If you have questions, leave them below.

    Spring hinges instead of closers

  2. Ian Greene says:

    I’ll probably be roasted for even suggesting this but would spring hinges be an option? If not, track arms closers?

  3. Cda says:

    Not a closure person but how about something like this

    Plus it can do double duty, and they can leave the doors open when needed

    I would use a surface closer on the left leaf and auto flush bolts on the right leaf. Use a coordinator and astragal for extra sound proofing.

    • Anthony Wan says:

      Oh and for the control on the right leaf, would either use spring hinges or a frame mounted closer with and extended arm.

  6. Terry Crump says:

    It’s probably a little too late now, but is a concealed floor-mounted closer an option?

  7. Rich says:

    Is the bevel truly on a diagonal as pictured? If so, how does the right door not interfere with the left. My original thought involved make the architect the door man and have him stand there til he learns something. My next thought is some version of a Rixon in the floor. Do they even make one with an offset for standard hinges? My third thought only goes back to making architects do a three year apprenticeship in the field installing the stuff they want to design. Last thought is to throw out the pull side restriction and use a Sentronic with a track. Similar to the above by Cda. Tied to the fire system and can hold open when wanted.

  8. BryanMcKeehan says:

    The drawing indicates beveled meeting stiles. They need to be square unless a coordinator is used.

  9. Scott Foley says:

    I haven’t used them myself yet but Check them out and let me know how it goes, they be the solution.

    They are Grade One and UL.

    Another one of those hair-brain ideas that no one challenged. The acoustics would have been better served by using an acoustical door than a skewed wood panel door. We know that having non-parallel surfaces in performing arts halls are a given, but this is totally unnecessary. How does the skew affect ADA approach and clearances? Can the left door leaf open 90 degrees. These plus all the previous comments make for an unnecessary complicated door set. One Architect’s comment.

  11. Ali says:

    As per my understanding PARKO closer with door coordinator with both combination will meet the requirement.
    Looking for feedback and suggestions.

  12. Khozema Kazi, AHC, FDAI says:

    1. the right door is inset, thus ideally it should have a raised barrel hinge. this door will not open more than 85deg.
    2. the right door can have top jamb mount closer with long arm (for deep reveal up to 8inches)

  13. alex sency says:

    why not use an LCN 4030 pull side mount and a longer shoe arm on the other door.
