      • Hall Entrance Refresh kits
        • These kits only apply to Otis offset integral  hanger hall door systems and Otis 7087 applied (offset cast iron) hall door systems, installed after about 1963 & mostly before 2005. Most Otis hall door systems carried very uniform designs over the years. One indicator is if Otis 6940 locks are present, the likelihood of having either hanger type mentioned above is very high. But please examine the hangers and use our Hall hangers and Tracks ID flyer if need be to help you identify what you have.

          To see what the kits contain, click on the link here . To order the kits with a UNITEC Representative, using one p/n per kit, see below.

      • Car Side Door Refresh Kits
        • In keeping with UNITEC’s extremely useful and popular HALL ENTRANCE REFRESH KITS (ERKs) released back in 2013, UNITEC has now released the mating equipment and kits for the CAR side for Otis equipment (CRKs). Otis has had a decent number of varying car fronts over the decades. The new kits UNITEC is offering cover the vast majority of the most common Otis car fronts. UNITEC recognizes it is sometimes a challenge knowing exactly which CAR tracks and hangers and door equipment may be present on the unit you are working. As a help to that challenge, please read through, and plan on bringing to your jobsite the flyer and survey form which outlines a large number of OTIS CAR Track shapes Otis has used. Knowing the track types helps the UNITEC REP define the CAR DOOR System you have in place. This Car Side Track Survey Form can be filled in and checked off as needed and returned to UNITEC for evaluation in helping you decide on the right MOD or REFRESH paths you may choose to take. Some situations WILL REQUIRE A COMPLETE CAR FRONT MOD, for example (see Screw Operator round tubular tracks in the attached). Those systems are no longer supported, but UNITEC has a FIX for that round
          track challenge.

          Please hand your lead mechanic on site the survey form and our Hanger and Track Types Flyer which will very likely allow you to verify the CAR door hanger type present. Rule of thumb for Otis Car systems: if you have 2.5” tall solid bar shape applied tracks, that will almost always by Otis AU hangers systems. Please click on the link below to view the kits available for Otis AU hangers. Second rule of thumb: if your CAR track system carries the formed Integral Car header track, your system is likely post 1976. The track portion of that one-piece roll formed car header construction carries a 2” tall dimension and the offset hangers shown would fit those tracks. For systems in that category, click on one of the links for Offset Integral/389BA_ in the year range that suits your installation. **Special note: the parts within the kits for 1977 to 1999 vs 2000 to 2005 systems appear identical to sight. However, anything on the car side after 1999 carried metric thread on both the hanger rollers and upthrust rollers. Please be certain you are ordering the correct kits for your applications. Imperial (1/2”) shaft thread parts will not properly fit into the hanger holes for the metric design parts.

      • Track and Hanger Sets
        • UNITEC provides very Robust Track and Hanger sets sets for all sorts of Door Modernization jobs as well as Entrance additions or rust outs. The drawings are provided here for reference for both the CAR & HALL side and for opening types: S/S, C/O & 2-Speed. Most installers are concerned with adapting to existing door tops and existing headers. No one wants to drill if they can help it. So UNITEC in offering these excellent and flexible sets, carries hanger options having various bolt spacing to adapt to both Otis and Non-Otis door tops. Hanger bolt spacing designs which have been manufactured for past jobs (not necessarily all stocked) include the most common for Otis which is 4-5/8”, but also: 4”, 4-1/8”, 3-1/4”, 3-3/4”, 4-1/4”, 4-3/4”, 5”. And the holes/slots can be suited for 3/8” or ½” bolts. You must allow ample lead time for any special hangers to be manufactured. However, you can be assured that we very commonly stock The 4-5/8”, 4-1/8” & 4” bolt spacing door hangers. In addition, do not get hung up on adapting to the header. If it is easy enough to remove the old, why not consider ordering new headers from UNITEC. (see our ‘Otis Integral Header Service Upgrade Solution’ page below). This is especially the case if either you already have Otis 6940 locks, or will be installing Otis 6940 locks. The headers are set up for this equipment. We will stock a number of typical headers, for the typical Otis opening sizes. Headers come pre-punched for the standard size openings (36”, 42”, 48”, 54”). And, these header kits are unhanded so no worrying about correct hand. When applying new UNITEC track and Hanger sets, avoid the labor Time and drill bit cost of drilling and applying nutserts. New headers is a no-brainer when any rust is present, or if you want to save the labor.
