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

1) What does RHR mean on the Don-Jo BP-1 bottom pivot, and will it work on a left hand door?
RHR is right hand reverse, and the BP-1-34-RHR is built for that handing only. Stand outside the door: if the hinges are on your right and the door pulls toward you, it's right hand reverse. A left hand or left hand reverse opening needs the opposite-hand pivot, not this one. Getting handing wrong on an offset pivot means the offset throws the door the wrong way and the leaf won't line up with the jamb prep.
2) How heavy a door can a Don-Jo BP-1 bottom pivot carry?
Up to 600 lbs. That covers heavy commercial wood and hollow metal doors, lead-lined doors, and thick fire doors that would overload a light-duty pivot. The BP-1 is classed heavy duty for commercial use, so it's the bottom pivot you reach for on high-traffic entries where a butt hinge set would sag.
3) Can I use this pivot on a 3-hour fire rated opening?
Yes. The Don-Jo BP-1 bottom pivot carries a 3-hour fire rating, so it can go on rated openings up to that classification. That's the spec institutional and MRO buyers need for stair enclosures, corridor doors, and occupancy separations where the door assembly has to hold its label.
4) Is the BP-1 an offset pivot or a center-hung pivot?
Offset hung, with a 3/4 inch offset. The pivot point sits 3/4 inch off the face of the door, so the door swings clear of the frame in one direction rather than rotating about its own centerline like a center-hung door. If your frame is prepped for center-hung pivots, this won't drop into it. Match the 3/4 inch offset to the prep already in the floor and head.
5) What size is the Don-Jo BP-1 bottom pivot plate, and will it fit my existing floor prep?
The plate measures 5-1/2 x 4-3/4 x 11/32 inches with a 3/4 inch offset. Lay those numbers against the mortise or surface area at the bottom of your jamb before ordering. If the existing pivot has a different offset dimension, the door will sit off its swing arc even if the plate screws down fine.
6) Does the BP-1 bottom pivot come with a matching top pivot?
No. The BP-1 is the bottom pivot only, packed one per box. An offset-hung door needs a top pivot or a top walking beam as well, plus the intermediate pivot if the door weight calls for one. If you want the whole set in one part number, an offset pivot set like the International Door Closers OP-3001 or OP-4001 (both 3/4 inch offset, handed, for flush doors) ships as a set instead.
7) Do I get the screws with the BP-1 pivot, or do I need to supply my own?
Fasteners are in the box: 8 wood screws and 8 machine screws. The wood screws handle a wood jamb or floor blocking, the machine screws handle hollow metal frames and tapped plates. Nothing else to source for the mounting itself.
8) Will the BP-1 hold up in a car wash bay, pool room, or coastal building?
Non-ferrous construction is the reason to pick it for those rooms. There's no steel to rust out at the floor line, which is exactly where a bottom pivot takes standing water, mop chemicals, and salt. Combined with the 600 lb rating, it suits wet high-traffic commercial openings.
9) Is the BP-1 pivot electrified or can it pass power through the door?
No. The BP-1 is a mechanical bottom pivot with no electrical provision. If the opening needs power to an electrified lock or exit device, plan on an electric power transfer or a door cord as a separate item, since the pivot won't carry it.
