Don-Jo BP-1-34-626-LHR – Frequently Asked Questions

1) What does left hand reverse mean on the Don-Jo BP-1 bottom pivot, and will it work on my door?
LHR means the door is hinged on the left as you stand outside it and swings toward you. The BP-1-34-LHR is built specifically for that handing, so it will not serve a right hand or a right hand reverse opening. Stand on the outside (the side you key or push from), note which edge carries the pivots and which way the door swings, and match that before ordering. Offset pivots like this are handed parts, not field-reversible.
2) How heavy a door will the Don-Jo BP-1 bottom pivot carry?
Up to 600 lbs. That covers most heavy commercial entrance doors, including thick fire-rated and lead-lined leaves that would tear out butt hinges. It is rated heavy duty and intended for commercial openings rather than residential interior doors.
3) Can I use this pivot on a 3-hour fire rated door assembly?
Yes. The BP-1 bottom pivot carries a 3-hour fire rating, which is the top tier and covers openings in 3-hour and 90-minute and lesser rated walls. That matters on stairwell and occupancy-separation doors where an unrated pivot would void the assembly listing.
4) Does the Don-Jo BP-1 come with mounting screws, or do I need to buy fasteners?
Fasteners are in the box: 8 wood screws and 8 machine screws, so you are covered whether you are anchoring into a wood frame and door or into hollow metal. What is not included is the matching top pivot or intermediate pivot, and an offset-hung door needs a top pivot or an offset arm closer at the head to complete the hang.
5) What size is the Don-Jo BP-1 bottom pivot plate?
The plate measures 5-1/2 by 4-3/4 inches with an 11/32 inch thickness. Check that footprint against the floor area at the jamb before you order, especially if there is an existing threshold, saddle, or mortised closer body competing for the same real estate.
6) Is there a non-handed offset pivot I can use instead so I do not have to track handing?
If the handing call is the problem, the International Door Closers OP-2700 is a 3/4 inch offset pivot set for flush doors that is non-handed, so one part covers either swing. The Don-Jo BP-1-34-LHR is handed to left hand reverse only. Note the OP-2700 is sold as a complete pivot set for flush doors, while the BP-1 is the bottom pivot on its own.
7) What finishes does the Don-Jo BP-1 bottom pivot come in?
Two: 613 satin bronze oil-rubbed and 626 satin chrome. 626 is the usual match for commercial hollow metal openings running satin chrome levers and closers, and 613 pairs with dark bronze storefront and wood door packages. The body is non-ferrous, so it holds up against corrosion at floor level where mopping and salt tracking are a constant.
8) Is the Don-Jo BP-1 an electrified pivot for power transfer to the door?
No, the BP-1 is a purely mechanical bottom pivot with no electrical option. If you need power to an electrified lock or exit device on an offset-hung door, run it through a separate door loop or electric power transfer rather than expecting it through this pivot.
9) I manage a building with mixed door hardware. Where does a heavy bottom pivot like this make sense over standard butt hinges?
Pivots carry the door load down into the floor instead of hanging it off the jamb, which is what you want on heavy leaves and high-cycle traffic where butt hinges sag and the door starts dragging. The BP-1 handles up to 600 lbs and is rated for commercial, heavy duty service, so it suits entrances in offices, schools, healthcare, retail, and multi-tenant residential. For a light interior wood door in an apartment, it is more pivot than the opening needs.
