Hager 5100-MLT-16-ALM – Frequently Asked Questions

1) What size do I order the Hager 5100 door closer in, or does one unit cover a range of doors?
Spring power on the 5100 is field adjustable from size 1 through size 6, so one part number covers a light interior office door up through a heavy exterior opening, with a maximum door weight of 330 lbs. You dial the size in at install instead of picking it on the order form. That is the practical reason to use it as a building standard: the stockroom carries one closer for corridor, entrance, and stair doors rather than four fixed sizes.
2) Will the Hager 5100 closer mount on a 1-3/8 inch door, or is it only for 1-3/4 inch?
Standard mounting on the 5100 is a 1-3/4 inch (44 mm) door, with 1-3/8 inch through 2-1/4 inch available as an option, so a thinner older interior door or a thicker exterior leaf both work. Watch the through-bolt hardware: the sex nut and bolt pack that ships in the box, the 5940, is specified for 1-3/4 inch doors, so a through-bolted install on any other thickness needs the SNB length that matches that door.
3) Is the Hager 5100 door closer handed? I have left hand and right hand doors on the same building.
Non-handed. The 5100 installs on a door of either hand with no field modification, so one closer works on every opening in the building regardless of swing. That also means a spare on the shelf can go on any door that fails, which is the usual reason a property manager or MRO stockroom picks a non-handed closer over a handed one.
4) Can the Hager 5100 be parallel arm mounted, or do I have to order a different arm for pull side versus push side?
All three mountings come in the box. The 5100 ships with the Tri-Pack arm covering regular (pull side), top jamb, and parallel arm, and the 5909 parallel arm bracket is included with it. Nothing extra to specify when ordering, and the installer decides mounting at the opening once they see which side the door swings and whether the frame face is usable.
5) Does the Hager 5100 closer meet a Grade 1 spec for school and hospital corridor doors?
BHMA Certified to ANSI A156.4 Grade 1, which is what a Grade 1 closer callout on a drawing is asking for, and it is also compliant with ANSI A117.1 and UL/cUL listed to UL10C and UL10B. Body is cast iron with a rust-inhibiting primer, full rack and pinion, heat-treated steel piston and triple heat-treated spindle. That combination is what puts it on schools, hospitals, and institutional corridor openings rather than light commercial interiors.
6) Can I use the Hager 5100 closer on a fire rated door?
Yes. The 5100 is UL/cUL Listed for up to 3 hours and carries a UL10C positive pressure rating, along with UL10B, so it can go on a fire rated opening including the positive pressure assemblies used in newer construction. Keep in mind a closer on a fire door has to self-latch the opening, so the latching valve adjustment matters here more than on a non-rated door.
7) We need the door to meet ADA opening force. Will the Hager 5100 work for an accessible entrance?
The 5100 is ADA compliant and built to ANSI A117.1 accessibility code, and because spring power adjusts across sizes 1 through 6 the opening force can be dialed to what the accessible opening needs rather than being fixed by the part number. Hager also recommends running anti-friction or ball bearing hinges with its closers, both to extend hinge life and to help the opening hit its ADA force numbers, so a worn plain bearing hinge on the same door can be what puts you over.
8) The door slams shut and blows open in the wind. Can the Hager 5100 be adjusted for that?
Both problems are adjustments on this closer. The 5100 has adjustable backcheck, sweep, and latching valves as standard: backcheck is what stops the door from being thrown open into the wall by wind or a hand truck, sweep controls the main closing speed, and latching controls the last few degrees so the door pulls into the latch instead of banging. All three are on the closer body, so an existing 5100 that slams usually needs a valve turned, not a replacement.
9) What comes in the box with the Hager 5100 closer, and what else do I need to buy to finish the install?
A complete install kit: 5101 closer body, 5102 cover, 5103 main arm assembly, 5104 standard screw pack, 5909 parallel arm bracket, and the 5940 SNB screw pack for 1-3/4 inch doors. Fasteners cover both substrates, with self-reaming and self-tapping wood and machine screws plus sex nuts and bolts. The one add-on to think about is the 5935 (2 inch) extra clearance parallel arm bracket, ordered separately when the frame face or a stop condition keeps the standard bracket from working.
10) How much clearance does the Hager 5100 door closer need, and what do I do if the frame is tight?
Clearance on the 5100 is listed at 4 inches. Where an overhead stop, a transom, or the frame face leaves less room to work with on a parallel arm mount, Hager makes the 5935 extra clearance parallel arm bracket at 2 inches, ordered separately from the 5909 bracket that ships in the box. Confirm the condition at the head of the opening before the closer goes up, because that is the detail that sends a crew back to the truck.
11) Cast iron door closer versus an aluminum body one, which should I use on a high traffic entrance?
Cast iron is the choice where the closer takes abuse. The 5100 uses a cast iron body with a rust-inhibiting primer, a one-piece seamless steel spring tube, and a heat-treated steel piston with a triple heat-treated spindle, and it is rated commercial for doors up to 330 lbs. That is the build for a school entrance, a hospital corridor, or any opening people shoulder through all day. A lighter aluminum body closer is aimed at low traffic interior doors, so if the opening is a private office or a closet door you are buying more closer than the door needs here.
12) What finishes does the Hager 5100 closer come in? I need it to match the closers already on our other doors.
Three finishes: Aluminum (ALM), Black (BLK), and Dark Bronze (DBZ). Aluminum is the usual match for clear anodized aluminum storefront and hollow metal, dark bronze for bronze anodized entrances, black where the frames are painted dark. Since the closer is non-handed and covers sizes 1 through 6, picking one finish lets a building run the same closer on every opening and keep a spare that matches whatever fails.
