CRL Jackson 20-101M-17 – Frequently Asked Questions

1) Will the CRL Jackson 20-101M-17 concealed closer fit my existing aluminum door header?
It drops into standard 1-3/4" x 4" (45 x 102 mm) or larger header extrusions, which covers most commercial aluminum storefront headers. The closer body itself measures 11-5/8 inches long by 3-11/16 inches wide, so the pocket has to accept that run inside the header. It's a concealed-in-frame closer, not a surface mount, so the header must already be prepped or cut for a concealed unit.
2) Do I get mounting clips with the CRL Jackson 20-101M-17 closer body?
No. This is a body-only closer, and mounting clips are not included. If you're replacing an existing concealed closer and the old clips are in good shape, you can reuse them. Otherwise you need to order the clip package that matches your header and door application separately, or the closer won't mount. Budget for that on the same order so the job isn't held up.
3) How wide and heavy a door will this CRL Jackson adjustable concealed closer handle?
Doors from 30 to 42 inches (762 mm to 1.07 m) wide, depending on the spring size you set and the closer function, and up to 250 lbs. That covers the typical single storefront leaf. A wider or heavier leaf than that is outside what this body is rated to control.
4) Can I use this closer on a barrier-free opening and still meet ADA opening force?
The spring power adjusts from Size 1 (barrier-free) through Size 4 (regular), so you can dial it down toward an ADA opening force. CRL Jackson is explicit that this doesn't guarantee compliance: set to ADA opening forces, the closer may not have enough spring power to control and close the door on a given site, depending on door size, stack pressure, and wind. On an exterior storefront leaf especially, verify the door actually latches at the lower setting before you commit to it.
5) Can this CRL Jackson closer replace a fixed spring size concealed closer I already have?
Yes, it retrofits existing fixed spring closers, and it's interchangeable with Jackson and similar-style overhead concealed closers. That's the main reason to pick the adjustable body: instead of stocking several fixed spring sizes across a building, you carry one body and set it in the field. Reuse the existing mounting clips if they're serviceable, since none come with the body.
6) What is a Grade 1 alternative to the CRL Jackson 20-101M-17 overhead concealed closer for a 250 lb door?
The Norton Rixson 73 Series is a heavy duty, Grade 1 center hung double acting overhead concealed door closer rated to 250 lbs, matching the 250 lb maximum door weight the CRL Jackson 20-101M-17 body carries. Both are concealed in frame mount closers, and the 73 Series ships with a cover plate. If the specification on the drawing calls out an ANSI/BHMA Grade 1 closer by name, the 73 Series answers it directly.
7) The door needs to swing past 105 degrees - what concealed closer should be used instead of the CRL Jackson 20-101M-17?
The CRL Jackson 20-101M-17 body is a non hold open closer set for a 105 degree swing, so an opening that has to travel further needs a different closer. The Sargent 269 is an overhead concealed door closer with 180 degree opening capability, heavy duty and Grade 1. That is the one to specify where the leaf swings back against a wall or into a vestibule that demands the wider arc.
8) Is a Norton Rixson 608 a direct replacement for a CRL Jackson adjustable spring power concealed closer?
Not on weight. The Norton Rixson 608 Series is a standard duty center hung overhead concealed closer for 200 lb doors, while the CRL Jackson 20-101M-17 body carries a 250 lb maximum door weight. On an opening at or under 200 lbs and center hung, the 608 covers the same concealed-in-header position; above that, look at the Norton Rixson 73 Series, which is rated to 250 lbs. The offset hung equivalent in the same standard duty family is the Norton Rixson 0608 Series, for aluminum doors up to 200 lbs.
9) For an aluminum storefront door on center hung pivots, what is the equivalent to the CRL Jackson 20-101M-17 concealed closer?
The Dorma RTS88 Series RTS01 is an overhead concealed door closer built for center hung side load, single or double acting, on aluminum door and frame, and it is non-handed. The CRL Jackson 20-101M-17 body is likewise single or double acting and mounts concealed in the frame. Both suit the aluminum storefront header; the RTS01 is specifically called out as non-handed, so one part covers left and right hand openings on a mixed entrance.
10) Does the 105 degree no hold-open closer stop the door from swinging past 105 degrees?
No. The 105 degree figure is where the hold-open function would engage on a hold-open model, and on this one there is none, so the door always returns to closed on its own. It doesn't act as a stop. If you need the door to stay open at 90 or 105 degrees for loading or deliveries, a hold-open version of the concealed closer is what you want instead. If you need the swing physically limited, that's an overhead stop or a stop in the pivot, ordered separately.
11) Can I adjust closing and latching speed separately on the CRL Jackson concealed closer?
Separate valves, yes. The closer has dual action valves, one for closing speed and one for latching speed, so you can slow the main sweep for occupant safety and still keep enough final snap to pull the latch home. That's the adjustment you'll be making on a windy exterior entrance where a single-speed sweep either slams or stalls short of latching.
12) What's the difference between a standard and extended spindle concealed closer body?
The spindle is the shaft that drives the door, and its length has to match the gap between the closer in the header and the top of the door, including any top rail or transom condition. CRL Jackson offers this adjustable body in both standard and extended spindle versions. Measure the existing spindle before ordering a replacement body, because a spindle that's too short won't engage the door and one that's too long won't seat in the header.
13) What other overhead concealed door closers could I use instead of the CRL Jackson adjustable body?
A few directions depending on what the opening needs. For a heavy leaf, the Norton Rixson 73 Series is a Grade 1 heavy duty center hung double acting concealed closer with a cover plate rated to 250 lbs, matching this one's weight capacity. The Sargent 268 is a Grade 1 heavy duty concealed closer with a cast iron body, and the Sargent 269 is the one to look at when you need a 180 degree opening rather than a 105 degree swing. On the aluminum storefront side, the Dorma RTS88 Series RTS01 is a non-handed center hung side load concealed closer for aluminum door and frame.
14) My door is offset hung, not center hung. Is there a concealed closer for that?
Concealed closers are built to suit how the door pivots, so the hung condition drives the selection. For an offset hung aluminum door, the Norton Rixson 0608 Series is a standard duty offset hung overhead concealed closer for aluminum doors up to 200 lbs. For center hung, the Rixson 608 Series and 700 Series are standard duty center hung closers for 200 lb doors. Confirm your pivot arrangement first, because the wrong hung type won't line up with the door at all.
15) Which double acting overhead concealed closers work for a door that swings both directions?
The CRL Jackson 20-101M-17 body is single or double acting, so it covers a leaf that swings both ways. Among the alternatives, the Dorma RTS88 Series RTS01 is double or single acting for center hung side load aluminum doors and frames, and the Norton Rixson 73 Series is a center hung double acting closer rated to 250 lbs with a cover plate. A door that only swings one direction does not need a double acting body, so confirm the swing before choosing.
16) Which concealed closers have a fully hidden arm, and which one leaves an arm exposed?
The CRL Jackson 20-101M-17 is a concealed in frame mount closer body that fits standard 1-3/4 inch by 4 inch or larger header extrusions, keeping the mechanism inside the header. Among the alternatives, the Sargent 278 is an overhead concealed door closer with an exposed arm, so the arm remains visible on the face of the door even though the body is concealed. The Sargent 268, with a cast iron body, and the Sargent 269 are the ones to look at when the appearance has to stay clean. All three Sargent bodies are heavy duty and Grade 1.
17) For a facility standardizing all concealed closers on one Grade 1 line, what are the options?
Three families carry a stated Grade 1 rating alongside the CRL Jackson 20-101M-17 body: the Sargent 268, 269 and 278 series, all heavy duty; the Norton Rixson 73 Series, heavy duty and rated to 250 lbs; and the Dormakaba ITS9613 in the ITS96 Series. Standardizing on one of those lines means a single closer family covers the openings, with the Sargent 269 handling doors that need 180 degree opening and the 278 the openings where an exposed arm is acceptable.
18) What is a simpler concealed closer choice than an adjustable spring power body for a light interior aluminum door?
The CRL Jackson 20-101M-17 body has adjustable spring power, which is what lets one part cover a range of door sizes and retrofit existing fixed spring closers. Where the opening is a single known size and the spring does not need to be dialed in, the Norton Rixson 700 Series and 608 Series are standard duty center hung concealed closers for 200 lb doors, and the Norton Rixson 0608 Series covers the offset hung version for aluminum doors up to 200 lbs. Those are the straightforward picks when there is no need to tune spring size on site.
19) Is the Dormakaba ITS9613 the same kind of closer as the CRL Jackson 20-101M-17?
Both are overhead concealed door closers that live inside the frame rather than on the face of the door. The Dormakaba ITS9613 is a Grade 1 closer in the ITS96 Series. The CRL Jackson 20-101M-17 is a commercial concealed in frame mount body, single or double acting, set for a 105 degree non hold open swing, measuring 11-5/8 inches long by 3-11/16 inches wide. Because the two come from different closer families, check the header pocket and the prep against the body dimensions before treating one as a drop-in for the other.
20) Is the CRL Jackson concealed closer suitable for a commercial entrance, or is it a residential unit?
Commercial. It's specified for commercial service, handles doors to 250 lbs and 42 inches wide, and mounts concealed in a storefront-style header extrusion. For a property manager standardizing entrance doors across a portfolio, one adjustable body covering Size 1 through Size 4 spring power means the same part number works on a light interior vestibule leaf and a heavier exterior entrance, set differently in the field.
