Dormakaba 80003-RH – Frequently Asked Questions
1) Do I need to order the Dormakaba 80003 preload spindle by hand?
Yes, handing matters. The 80003 preload spindle comes as left hand and right hand, and you pick the one that matches the swing of the door the BTS floor closer is under. It's a single-acting spindle, so the door only swings one way and the hand isn't interchangeable once installed.
2) What does the 3 degree preload on a Dormakaba 80000 series spindle actually do?
The preload puts extra closing pressure on the door so it stays firmly in the closed position instead of resting loose against the stop. On the 80003 that's 3 degrees of preload built into the spindle. It's also the fix when a floor closer or pivot was templated slightly off and the door won't sit square when closed, since the preload takes up that error.
3) Will a preload spindle work on an offset-hung or double-acting door?
No. The 80003 is built for center-hung, single-acting BTS installations, where the pivot point sits in the center of the door thickness and the door swings one direction only. A double-acting door or an offset-hung arrangement needs the spindle made for that application, not this one.
4) Can I swap the spindle on a BTS floor closer without pulling the closer out of the floor?
The 80000 series spindles are interchangeable, which is the point of the design: the spindle is a replaceable part on the BTS closer rather than a fixed piece of the body. So a door that needs a different clearance or added preload is a spindle change, not a closer replacement.
5) Is the Dormakaba 80003 spindle rated for a high traffic commercial entrance?
It's a commercial Grade 1 part, the top ANSI/BHMA duty tier, which is what you want under a storefront or lobby door that cycles all day. It is a replacement spindle for a BTS floor closer, not the closer itself.
6) Does the Dormakaba 80003 include the floor closer or the top pivot?
No, the 80003 is the spindle alone, a replacement part for a BTS series floor closer. The closer body, cement case, top pivot and any door rails are ordered separately.
