Imperial USA IMPTH1100-INT-AL – Frequently Asked Questions

1) Do I need an intermediate pivot on a tall aluminum door, and how many?
Intermediate pivots come into play on doors taller than 83 inches, where the middle of the door needs help staying in line with the top and bottom pivots. Up to 90 inches in height, one TH1100-INT is enough. Past that, add another intermediate pivot for each additional 30 inches of height.
2) What door thickness does the Imperial TH1100-INT pivot fit?
1-3/4 inches, the standard commercial door thickness. It is a single-thickness set, so a thinner 1-3/8 inch leaf is not what this pivot is cut for.
3) Is the TH1100-INT a complete pivot set or do I still need top and bottom pivots?
It is the intermediate pivot only, the middle support that keeps a tall leaf aligned. You still hang the door on a top and bottom pivot. For a 3/4 inch offset opening the Dormakaba 75120 is a 3/4 inch offset full mortise top pivot, which matches the same offset dimension.
4) The frame is prepped for a 1-1/2 inch offset. Will the TH1100-INT work?
No. The Imperial USA TH1100-INT is a 3/4 inch offset application, so it needs a 3/4 inch offset hanging. For a 1-1/2 inch offset prep, the Dormakaba 15220 is a 1-1/2 inch offset brass right hand intermediate pivot in satin chrome, heavy duty and fire rated. If instead the opening is 3/4 inch offset and full mortise prepped, the Dorma 75220 is the 3/4 inch offset hung full mortise intermediate pivot, with the Dormakaba 75120 as the matching 3/4 inch offset hung full mortise standard top pivot.
5) What is the closest equivalent to the Imperial USA TH1100-INT intermediate pivot from another brand?
The Dorma 75220 is the nearest match in the offset intermediate class. It is a 3/4 inch offset hung full mortise intermediate pivot, the same 3/4 inch offset geometry the TH1100-INT is built around, and Dormakaba rates it heavy duty and fire rated. The TH1100-INT is a 3/4 inch offset intermediate pivot for aluminum doors up to 125 pounds with a full race ball bearing and Oilite bronze bushing. The difference to check before you swap: the 75220 is a full mortise pivot, so the door and jamb prep is a mortise pocket rather than the surface-applied arrangement the aluminum-door TH1100-INT uses.
6) What intermediate pivot should I use on an aluminum storefront door instead of the TH1100-INT?
Kaba Ilco makes three intermediate pivot series built specifically for aluminum doors and frames: the IP-10 Series, the IP-12 Series, and the IP-22 Series. All three are standard duty. The IP-12 Series is non handed, which matters if you are stocking one part for both leaves of a pair rather than pulling a left and a right. The Imperial USA TH1100-INT covers the same application on aluminum doors up to 125 pounds and works on both flush face frame installations and 1/8 inch recessed door applications.
7) I need a fire rated intermediate pivot. What are my options?
Dormakaba publishes a fire rating on two intermediate pivots. The 75220 is a 3/4 inch offset hung full mortise intermediate pivot, heavy duty and fire rated. The 15220 is a 1-1/2 inch offset brass right hand intermediate pivot in satin chrome, also heavy duty and fire rated. Match the offset to the door prep you already have: 3/4 inch and 1-1/2 inch offsets are different hangings and are not interchangeable in the same frame. Note the 15220 is handed right hand, so a left hand opening needs the opposite hand.
8) Can I use a top pivot or bottom pivot in place of an intermediate pivot?
No. An intermediate pivot like the Imperial USA TH1100-INT carries the middle of a door taller than 83 inches and keeps it in line with the pivots at the top and bottom, so it is an addition to a hanging, not a replacement for either end of one. The Dormakaba 75120 is a 3/4 inch offset hung full mortise standard top pivot and the Hager 497 is a heavy duty forged bronze full mortise bottom pivot hinge with ball bearing. Those are the head and sill positions. On a tall door you specify all three: top, bottom, and one intermediate for doors up to 90 inches, plus another intermediate for each additional 30 inches.
9) Do I have to specify handing when ordering the Imperial TH1100-INT?
No handing choice is made on the TH1100-INT; the only thing to pick is finish, aluminum or duronodic. That differs from some offset intermediate pivots that are handed, such as the Dormakaba 15220, which is a right hand 1-1/2 inch offset pivot and has to be ordered to the swing of the door.
10) Can I adjust an intermediate pivot after the door is hung if the leaf sits off?
The TH1100-INT allows easy vertical adjustment, so the middle support can be brought into line after the leaf is set rather than requiring the whole door to come back down. Note the fully retractable case hardened jamb pin, which speeds installation, is a feature of the TH1120 and TH1121 pivots, not this set.
11) My storefront doors are 1/8 inch recessed rather than flush. Does the TH1100-INT still apply?
Both work. The TH1100-INT is made for flush face frame installations and for 1/8 inch recessed door applications, so the same part covers either frame condition. If your opening is an Arch or Vistawall style 1/8 inch recessed frame and you need the full hanging set rather than the middle pivot, the Kaba Ilco IL-OP-10 Series is a 1/8 inch recessed Arch/Vistawall pivot set.
12) What is the difference between the Kaba Ilco IL-OP-10 Series pivot set and an intermediate pivot for a recessed aluminum door?
The Kaba Ilco IL-OP-10 Series is a 1/8 inch recessed Arch/Vistawall pivot set, standard duty, made to hang the door on those specific storefront systems. The Imperial USA TH1100-INT is an intermediate pivot for 3/4 inch offset applications and supports the middle of a tall door; it covers both flush face frame installations and 1/8 inch recessed door applications. So the IL-OP-10 is the hanging set for a recessed Arch or Vistawall opening, while the TH1100-INT is the mid-height support you add above 83 inches of door height.
13) Is a reinforcing pivot the same thing as an intermediate pivot?
They are different parts. The Hager 253 is a full surface reinforcing pivot sized for 4-1/2 inch wide hinges, zinc plated, heavy duty, for 1-3/4 inch doors. It reinforces a hinge-hung door, so it goes on an opening already carried on butt hinges. The Imperial USA TH1100-INT is an offset intermediate pivot for a pivot-hung door, for use on flush face frame installations and 1/8 inch recessed door applications, and it cannot be used on center hung doors. Both suit a 1-3/4 inch door thickness, but they belong to two different hanging methods and one does not substitute for the other.
14) Which offset pivot sets are non handed so I do not have to order left and right?
The Kaba Ilco IP-12 Series intermediate pivots for aluminum doors and frames are non handed, so one part covers either hand. By contrast the Dormakaba 15220 is a right hand intermediate pivot, meaning a left hand opening takes the opposite part number. On a pair of doors or a mixed-hand fleet of tall storefront leaves, the non handed part keeps the stocked count down.
15) Should I specify a heavy duty intermediate pivot instead of a standard duty one?
It depends on the leaf. Among intermediate pivots, Dormakaba rates the 75220 3/4 inch offset full mortise and the 15220 1-1/2 inch offset brass as heavy duty, while the Kaba Ilco IP-10, IP-12, and IP-22 Series intermediate pivots for aluminum doors are standard duty. The Imperial USA TH1100-INT is built for commercial use on aluminum doors up to 125 pounds with a full race ball bearing and Oilite bronze bushing. A light aluminum storefront leaf sits comfortably in the standard duty range; a heavy or high-cycle entrance is where the heavy duty full mortise parts are specified.
16) What finishes does the Imperial TH1100-INT intermediate pivot come in?
Two: AL aluminum and DU duronodic. Aluminum matches clear anodized storefront, duronodic matches the dark bronze anodized framing that is common on older commercial entrances. Pick the one that matches the frame, not the door hardware, since the pivot sits in the jamb line.
17) What is inside the TH1100-INT pivot, and will it hold up on a high-traffic entrance?
The body is precision aluminum diecast, and the bearing package is a full race ball bearing with an Oilite bronze bushing. That is the arrangement built for repeated swing cycles rather than an occasional-use door. It is a commercial pivot, not residential.
18) Does the Imperial USA TH1100-INT come in a finish that matches a bronze storefront?
The TH1100-INT intermediate pivot set is offered in AL aluminum and DU duronodic, so duronodic is the dark bronze-tone option for a bronze anodized storefront. If the rest of the opening is chrome, the Dormakaba 15220 intermediate pivot is a satin chrome brass part, and the Hager 253 reinforcing pivot carries a zinc plated finish. Finish choice on the pivot does not change the hanging: match the offset and the door weight first, then the finish.
