Imperial USA IMPTH1112-RH-AL – Frequently Asked Questions
1) Do I need to order the TH1112 Amarlite pivot left hand or right hand?
Handing matters. The TH1112 is sold as a handed set, left hand or right hand, and each is offered in Aluminum or Duronodic finish. Stand outside the door: if it swings away from you on hinges to your left, that's left hand. Order the hand that matches the opening, since an offset pivot set can't be flipped in the field.
2) My aluminum door is sagging at the top corner. Will replacing it with the TH1112 pivot set fix that?
Sagging usually means the door's weight is hanging off the top rather than being carried at the floor. With the TH1112, the entire weight of the door rests on the floor-mounted pivot, which is what prevents sag. It runs a full race ball bearing design so the door keeps swinging smoothly under that load. Weight limit is 125 lbs on an 83 inch door; heavier or taller leaves need more support.
3) What is the closest equivalent to the Imperial USA TH1112 offset pivot for a 1/8 inch recessed aluminum door?
The Imperial USA TH1112 is a 3/4 inch offset pivot advised for 1/8 inch recessed door applications on aluminum doors and frames. The nearest equivalent in the same 1/8 inch recessed aluminum-door territory is the Kaba Ilco IL-OP-10 Series 1/8 inch Recessed Arch/Vistawall Pivot Set, a standard duty pivot set. The difference is the frame family each is cut for: the TH1112 is an Amarlite style pivot, while the IL-OP-10 Series is an Arch/Vistawall pattern. Confirm which storefront line the existing door and frame came from before ordering either, because the offset geometry is common but the prep is not.
4) Can I use an intermediate pivot in place of the Imperial USA TH1112?
No. The TH1112 is an offset pivot set that hangs the door, with the entire door weight resting on the floor mounted pivot. An intermediate pivot is a mid-height support added between top and bottom, not a replacement for either. The Kaba Ilco IP-10 Series, IP-12 Series and IP-22 Series intermediate pivots for aluminum doors and frames are all standard duty, and the Dormakaba 15220 1-1/2 inch offset brass right hand intermediate pivot and Dorma 75220 3/4 inch offset hung full mortise intermediate pivot are heavy duty. Intermediate pivots are what to add on aluminum doors taller than 83 inches, alongside the offset set, not instead of it.
5) Is the TH1112 pivot okay for an exterior entrance door?
Yes on exterior openings. The TH1112 pivots are weather resistant for exterior door use, and the casing is cast aluminum, so it stays light and holds up outside. It's a commercial-grade part, not a residential one.
6) How much can I adjust the door height after the TH1112 pivots are installed?
Vertical adjustment on the TH1112 is 1/8 inch. That's enough to true up the bottom rail clearance and get the door sitting square in the frame, but it won't correct a frame that's badly out. Set your floor pivot location carefully, because 1/8 inch is all the correction you get afterward.
7) Are Amarlite style offset pivots secure, or can someone lift the door off?
The TH1112 is tamper proof in the locked position while still being easy to remove and replace for service. Security is highest when the door is running an Adams Rite cam. Unlocked, the set comes apart for maintenance without drilling out anything.
8) What is the difference between an offset pivot and a center hung pivot on an aluminum door?
An offset pivot like the TH1112 sets the pivot point off the door edge, 3/4 inch here, so the door swings clear of the frame and works with a flush face frame or a 1/8 inch recessed application. Center hung pivots put the pivot on the door's centerline and let the leaf swing both ways, which is a different opening entirely. If you're replacing pivots on an existing aluminum storefront, match what's there: offset for offset, and match the offset dimension.
9) How many pivots come in one order of the TH1112, and do I need anything else?
One set is sold per package, so a single order covers one door leaf. A pair of doors takes two sets, one per leaf, each ordered to its own hand. On doors over 83 inches you'll also need intermediate pivots on top of the set.
10) Does the Hager 497 bottom pivot replace the Imperial USA TH1112 on an aluminum storefront door?
They are not interchangeable. The Hager 497 is a heavy duty forged bronze full mortise bottom pivot hinge with ball bearing, a full mortise part that requires the leaf and frame to be routed for it. The TH1112 is a 3/4 inch offset pivot for aluminum doors and frames in the Amarlite pattern, advised for 1/8 inch recessed applications and supplied handed, left or right. Aluminum storefront leaves are not normally prepped for a full mortise bottom pivot, so treat the 497 for hollow metal or wood openings and stay with the offset pattern on storefront.
11) What is the difference between a reinforcing pivot like the Hager 253 and an offset pivot set like the TH1112?
The Hager 253 is a full surface reinforcing pivot for 4-1/2 inch wide hinges in a zinc plated finish, heavy duty, for 1-3/4 inch doors. It reinforces a butt hinged door, mounting on the surface alongside the hinges. The Imperial USA TH1112 is an offset pivot set that hangs the door on a pivot instead of hinges, with the leaf swinging on a floor mounted bottom pivot and a top pivot at the header. If the opening already runs butt hinges and just needs support, that is reinforcing pivot work; if the door swings on pivots, the offset set is the part.
12) Which offset pivots are non handed if I want to stock one part for both door swings?
The Imperial USA TH1112 is handed, ordered left handed or right handed, in aluminum or duronodic finish. Among intermediate pivots for aluminum doors and frames, the Kaba Ilco IP-12 Series is non handed, so one part covers either swing; the Dormakaba 15220 1-1/2 inch offset brass intermediate pivot is right hand. For a fleet of storefront doors, note that handing on an offset set is determined at the opening, so record swing per door before consolidating a stock list.
13) Which finish of the TH1112 pivot matches the rest of my storefront doors?
Two finishes are made: AL Aluminum, which matches clear anodized aluminum storefront, and DU Duronodic, the dark bronze anodized look used on bronze-tone entrances. Both are available in left hand and right hand. Pick the one matching the door frame, since the pivot plate shows at the top and bottom of the leaf.
