Frequently Asked Questions

How many hinges does a commercial door need?
A door up to 5' tall needs two hinges, plus one more for each additional 30" of height or part of it. That means three hinges on a standard 7' door and four on an 8' door.

What is the difference between ball bearing and plain bearing hinges?
Ball bearing hinges have hardened steel ball bearings between the knuckles, so the door turns with less friction and the hinge wears less. Plain bearing hinges pivot metal on metal with no bearings and suit low-traffic doors. PDQ recommends ball bearing hinges on any door with a closer.

What is a non-removable pin hinge?
A non-removable pin (NRP) hinge has a pin that cannot be tapped out while the door is closed, so the door cannot be lifted off by pulling the pins. It should be specified on out-swinging doors. PDQ includes a non-removable pin on every 2 and 4 ball bearing hinge.

PDQ 35STSHP4545626 – Frequently Asked Questions

1) What exactly comes in the PDQ 35STSHP4545 hinge set?
The 35STSHP4545 is a prepackaged three-hinge set for one 7 foot commercial door: two self-closing spring hinges plus one ball bearing hinge, all 4-1/2 x 4-1/2 inches, full mortise. The two spring hinges do the closing work and the ball bearing hinge carries the swing. Screws are in the box too: 12-24 x 1/2 inch flat head machine screws for metal frames and #12 x 1-1/4 inch flat head wood screws for wood.
2) Can I use a spring hinge set instead of a door closer on a fire door?
That's what this set is for. The two SH spring hinges self-close the door, so you get latching without hanging a closer on the frame, and PDQ's SH Series spring hinges are UL listed. PDQ hinges conform with NFPA 80-2010 Section 6.4.3.1. Where a door gets heavy traffic or needs controlled closing speed and latch check, a closer is still the better tool: spring hinges give you closing force, not control.
3) Is three hinges enough for a 7 foot commercial door?
Yes. A door up to 5 feet tall takes two hinges, with one more for each additional 30 inches of height or part of it, which puts a standard 7 foot door at three. That is exactly what the 35STSHP4545 set contains. An 8 foot door needs four, so this set alone won't cover it.
4) Will this steel hinge set hold up on an exterior door?
No. The 35STSHP4545 is satin chrome plated steel, which PDQ specifies for interior doors in non-corrosive environments. For an exterior opening or a corrosive environment (coastal, pool, kitchen, wash-down), move to a stainless steel PDQ 35 Series hinge instead.
5) Will a 4-1/2 x 4-1/2 full mortise hinge drop into my existing hinge prep?
4-1/2 x 4-1/2 is the standard commercial full mortise size, so it fits a frame and door already prepped for 4-1/2 inch square hinges without rework. The 35 Series is swaged with 1/16 inch clearance between the leaves when the door is closed. If your existing prep is 4 x 4 or a 5 inch hinge, the mortise depth and screw pattern won't line up.
6) Why does the PDQ set mix one ball bearing hinge with two spring hinges instead of using three spring hinges?
The ball bearing hinge handles the pivoting load with hardened steel ball bearings between the knuckles, so the door turns with less friction and the hinge wears slower, while the two spring hinges supply the closing force. Running all three as springs would add force without adding bearing support. PDQ recommends ball bearing hinges on any door that is being driven closed.
7) What finish is PDQ 626 and will it match my other US26D hardware?
626 is satin chrome plated steel, which is BHMA 652 / US26D. It matches the satin chrome / satin chrome-plated locksets, closers and exit devices commonly specified as US26D or 626 across school, healthcare and multifamily openings, so it blends with the standard brushed-nickel-look commercial finish.
8) Do these hinges have a non-removable pin for an out-swinging door?
The ball bearing hinge in the set does. PDQ includes a non-removable pin as standard on every 2 and 4 ball bearing hinge, so the pin cannot be tapped out with the door closed and the door can't be lifted off its pins. NRP should be specified on out-swinging doors, which is the usual case on exterior and stair openings.
9) Is this hinge set appropriate for apartment corridor and stairwell doors?
Yes, that is its intended ground. PDQ lists education buildings, healthcare facilities and multifamily buildings as typical applications, and a self-closing spring hinge set is the usual way to keep a dwelling-unit or corridor door latched. Since PDQ hinges conform with NFPA 80-2010 Section 6.4.3.1 and the SH spring hinges are UL listed, they suit the self-closing fire door openings that dominate those buildings.
10) When should I step up to a 4 ball bearing heavy weight hinge instead of this set?
Match the hinge to door weight and traffic. The 35STSHP4545 pairs standard-weight spring hinges with a ball bearing hinge, which suits a normal commercial door needing self-closing. For a heavy door, a wide or lead-lined leaf, or a high-cycle opening, go to PDQ's 4 ball bearing heavy weight 35 Series hinge and add a separate closer. Plain bearing hinges are only for low-traffic doors and PDQ does not recommend them anywhere a door is being driven shut.
11) Do I need to order screws separately for a hollow metal frame?
No. Every PDQ hinge is packed with both fastener types: 12-24 x 1/2 inch flat head machine screws, which are what thread into a hollow metal frame, and #12 x 1-1/4 inch flat head wood screws for wood frames and wood doors. One set covers either condition.
12) Does handing matter when I order this PDQ spring hinge set?
Full mortise butt hinges like the 35 Series are non-handed, so the same 35STSHP4545 set hangs a left or right hand door. What you do set in the field is the spring tension on each spring hinge, adjusted so the door closes and latches reliably.
