Installation & Operation

  1. Review manufacturer specifications and verify floor preparation requirements for cast iron cement case installation including proper concrete depth and reinforcement.
  2. Use manufacturer-provided templates to mark mounting locations accurately ensuring proper alignment with door pivot points and frame clearances.
  3. Prepare floor opening according to specifications and install cement case with cast-in extensions for positive anchorage in concrete.
  4. Install 180 top pivot (included) and M19 intermediate pivots (ordered separately) based on door height - doors 60" to 90" require one intermediate pivot with additional pivots for each 30" increment.
  5. Adjust separate independent valves for closing speed, latch speed, and backcheck to achieve desired door operation and configure dead stop for specified opening degree (85°, 90°, 95° or 105°).
  6. Test device operation throughout full range of motion and verify proper latching, closing sequence, and dead stop function. Refer to manufacturer documentation for complete installation details and valve adjustment procedures.

Norton Rixson SEC27-180N RH 626 – Frequently Asked Questions

1) Will the Rixson SEC27-180 floor closer handle a 600 lb detention door?
Yes. The SEC27-180 is rated for interior security doors up to 650 lbs, with maximum door width of 4'0". It's built for detention and behavioral health openings, using a cast iron cement case with cast-in extensions for floor anchorage and a forged bottom arm.
2) Do I have to specify hand when ordering a SEC27-180 floor closer?
Yes, handing is not field-reversible on this one. The SEC27-180 is a single-acting, handed closer, so it's ordered as either Left Hand or Right Hand. Get it wrong and the closer won't work on the opening.
3) What pivots do I need to order with a Rixson SEC27-180?
The 180 top pivot comes with the closer. Intermediate pivots do not: M19 intermediate pivots are ordered separately, and doors 60" to 90" tall need one, with an additional pivot for every 30" of height beyond that. On a tall detention door that's an easy line item to miss.
4) Is the SEC27-180 an offset hung or center hung floor closer?
Offset hung, at 3/4" offset. That means the door pivots off a point set 3/4" in from the frame, which is the standard arrangement for single-acting doors that swing one way only. If your opening is center hung and swings both directions, this is the wrong closer.
5) Can the SEC27-180 stop the door at 90 degrees instead of letting it swing all the way open?
Yes. The closer opens to 180 degrees and has a built-in positive dead stop that can be set at 85, 90, 95 or 105 degrees. That's a mechanical stop in the closer itself, so you don't need a separate floor or wall stop in the room, which matters in behavioral health spaces where surface-mounted hardware is a problem.
6) What is the closest alternative to the Norton Rixson SEC27-180 floor closer for a center-hung door instead of a 3/4 inch offset-hung security door?
The SEC27-180 is a single-acting, handed 3/4 inch offset-hung closer built specifically for interior security doors up to 650 lbs in detention and behavioral health work, with a cast iron cement case and built-in positive dead stop. If the opening is not an offset-hung security door, the Dormakaba Dorma BTS75V is a floor closer body supplied with a cement case, less spindle, rated Grade 1 and configured NHO non hold open. Both are Grade 1 floor closers with a cement case, and neither offers hold open; the difference is that the SEC27-180 is handed and dedicated to offset-hung security doors while the BTS75V is a general concealed floor closer body ordered without the spindle.
7) Does the Rixson SEC27-180 hold the door open?
No hold open on this model. It's a non hold open closer, so the door returns to closed every cycle. In detention and secure healthcare work that's usually the point. If you need hold open, the SEC27-180 is not the unit.
8) Is the SEC27-180 floor closer ANSI Grade 1?
Yes, certified to ANSI/BHMA A156.4 Grade 1, the top grade for door controls, and rated high traffic commercial. That's the line most institutional and government specs call for on secure openings.
9) How do you adjust closing speed on a Rixson SEC27 floor closer?
Three separate independent valves: one for closing speed, one for latch speed, one for backcheck. They're adjusted independently, so you can slow the swing across most of the arc, keep enough latch speed to throw the bolt on a heavy security door, and use backcheck to stop the door being thrown into the wall. Set them after the case is anchored and the door is hung.
10) Can I install a floor closer like this without pouring a new cement case?
The SEC27-180 needs a cast iron cement case set into the floor, with cast-in extensions for anchorage, and it can be installed with a floor plate or into a threshold with vertical door adjustment. If you're retrofitting and the existing recess is a different make, plan on floor work. A Dormakaba alternative we carry, the BTS75V, is also supplied with its own cement case (less spindle) if you're pricing a second option, and the BTS-80 is offered as a body only unit for dropping into an existing case.
11) If I need a floor closer that holds the door open, can I use the Norton Rixson SEC27-180?
No. The SEC27-180 has no hold open feature; it is a single-acting closer with a built-in positive dead stop that limits travel at 85, 90, 95 or 105 degrees rather than holding the door. The Dormakaba Dorma BTS75V is also supplied non hold open, so it does not solve that requirement either. If hold open is required at the opening, specify a floor closer ordered in a hold open configuration.
12) For standardizing floor closers across a facility, which of these carry an ANSI Grade 1 rating?
The Norton Rixson SEC27-180 is certified to ANSI/BHMA A156.4 Grade 1 and rated for high traffic commercial use. The Dormakaba Dorma BTS75V is also listed as Grade 1. The Dormakaba Dorma BTS80 is listed as heavy duty. Where the specification calls out A156.4 Grade 1 by standard number, the SEC27-180 is the one that states the standard as well as the grade.
13) What finishes does the Rixson SEC27-180 come in?
Thirteen finishes on the exposed parts, in both hands: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed bronze, 613E dark oxidized satin bronze, 618 bright nickel, 619 satin nickel, 622 black painted, 625 bright chrome, 626 satin chrome, plus BSP black suede powder and WSP white suede powder. The powder coats are the usual pick when matching detention hardware rather than architectural trim.
14) Will moisture in the slab damage a floor closer?
The SEC27 is a sealed closer, which keeps moisture from getting in between the closer body and the cement case. That's the usual failure mode on floor closers set in slabs that see mopping or wash-down, and it's why the case is cast iron rather than sheet steel.
