Norton Rixson 252050L-626 – Frequently Asked Questions

1) Does the Rixson 252050L arm pack work on a right-hand door?
No. The 252050L bottom arm assembly is built in left-hand configuration only, so the geometry and clearances match a left-hand opening. Put it on a right-hand door and the arm will not line up with the closer spindle. Order the right-hand version of the bottom arm pack for those openings.
2) What exactly does the Norton Rixson 252050L arm pack include?
It is a bottom arm assembly: the arm itself, the clamp/shoe that grips the door, and the fasteners needed for a standard retrofit. The closer body, cement case, spindle and top pivot are not part of it. If the closer itself is worn out rather than just the arm, you are replacing the unit, not this pack.
3) Which Rixson floor closers does this bottom arm pack fit?
It is an OEM replacement arm for Rixson 25 Series center-hung floor closers, and it mounts to the existing 25 Series preparation so you are not recutting the floor or the door bottom. Confirm the closer body in the case is a 25 Series before ordering.
4) Can a Dorma BTS75V or BTS80 floor closer be used in place of the Norton Rixson 252050L arm pack?
No - they are different classes of item. The Norton Rixson 252050L is a bottom arm assembly that couples the door to the closer spindle on an existing 25 Series center-hung floor closer, not a closer itself. The Dorma BTS75V is a floor closer body only, supplied with cement case and less spindle, and the Dorma BTS80 is a concealed floor closer body only. If the closer body in the floor is worn out, a BTS75V or BTS80 is the replacement to look at; if the body still controls the door properly and the door wobbles or sits out of alignment, the 252050L arm pack is the part that addresses it.
5) If I am replacing the whole center-hung floor closer instead of just the arm, what should I look at for a non-hold-open Grade 1 unit?
The Dorma BTS75V is a Grade 1 floor closer body with a non-hold-open function, supplied with a cement case and less spindle. That matches the operating character of a Rixson 25 Series opening served by the 252050L arm pack, which is also Grade 1 under ANSI/BHMA A156.4 and has no hold open feature. Note the BTS75V ships less spindle, so the spindle and arm hardware for the opening are handled separately.
6) Will the 252050L arm pack fit a Dorma floor closer?
No. The Norton Rixson 252050L is built as a direct OEM fit for Rixson 25 Series center-hung floor closer preparations and matches that spindle and arm geometry. A Dorma BTS75V or BTS80 is a separate floor closer body and uses its own arm and spindle hardware - the BTS75V is in fact supplied less spindle. Keep the arm pack with a Rixson 25 Series closer and source Dorma arm hardware for a Dorma body.
7) Is this arm for a single-acting or double-acting floor closer?
Single acting. The 252050L arm is specified for single-acting door swing, meaning the door swings one direction only. A double-acting center-hung installation uses different arm and pivot hardware.
8) Is the Rixson 252050L rated for a high-traffic entrance?
Yes. It carries an ANSI/BHMA A156.4 Grade 1 rating, heavy duty, and is specified for high-traffic commercial openings, which is the class of hardware you want on a lobby or school entry door that cycles all day.
9) Will replacing the bottom arm fix a door that wobbles or drags on a floor closer?
If the play is in the arm or the clamp/shoe that couples the door to the closer spindle, yes. The bottom arm sets alignment for the sweep, latch and backcheck, and a worn arm shows up as wobble and a door that no longer closes square. If the closer itself is leaking oil or has lost control, the arm pack will not correct that.
10) Can I use the 252050L arm with an offset-pivot floor closer?
No. It is made for center-hung floor closer installations, where the spindle sits on the door centerline. Offset hung openings use a different bottom arm geometry, and the clamp/shoe will not locate correctly on that prep.
11) What is the difference between the Dorma BTS80 and BTS75V if I am replacing a heavy traffic floor closer rather than the arm?
Both are body-only floor closers. The BTS80 is rated heavy duty and carries no fire rating. The BTS75V is listed as Grade 1 with a non-hold-open function and comes with a cement case, less spindle. The Norton Rixson 252050L arm pack sits alongside either decision only as a service part - it is the left-hand bottom arm assembly for a 25 Series center-hung closer and does not replace a closer body.
12) Does this Rixson arm give me a hold-open function?
No hold open. The 252050L arm pack is non hold open, so the door returns and latches every cycle. If the opening needs hold open, that function lives in the closer body, not the arm.
13) What finish does the Norton Rixson floor closer arm pack come in?
626 satin chrome, which is the standard commercial match for most lever and pull hardware. That matters less than usual here since the bottom arm sits at the door bottom under the shoe, but it will match satin chrome trim on the rest of the opening.
