Calibre Door Closers CA3311-S-DP – Frequently Asked Questions

1) Will the Calibre CA3311-S-DP concealed closer fit my storefront header, or do I need a deeper one?
Header space is the first thing to check on an overhead concealed closer, and the CA3311-S-DP needs a header as small as 1-3/4" x 4". If your aluminum storefront header meets or exceeds that pocket, the unit body drops in. Anything shallower and no overhead concealed closer of this size will fit, and you would be looking at a surface mounted closer instead.
2) Do I need to order the Calibre CA3311 closer left hand or right hand?
No handing to specify. The CA3311-S-DP is non-handed and works left hand or right hand, and the same unit covers center hung or offset hung doors. What you do specify is the top arm: 'S' side loading is standard and ships with this model, but offset hung applications need a 'JO' or 'VO' arm called out on the order.
3) Which Calibre top arm do I need for my door's top rail depth?
Match the arm to the top rail depth. The CA3010-S side loading arm suits a 1/2" depth top rail and is what comes standard on the CA3311-S-DP. End loading options: CA3010-K for 5/8", CA3010-PT for 7/8", CA3010-A for 1". For offset hung doors, the CA3010-JO mortises into a 9/16" top rail and the CA3020-VO is a surface type needing 7/8".
4) Is the bottom pivot included with the Calibre CA3311-S-DP, or is that a separate order?
Included. The CA3311-S-DP ships with the CA3010-DP adjustable dual purpose bottom pivot set and the CA3010-FS anchor set with all mounting hardware. If your opening needs a floor mount pivot instead, that is the CA3010-G; for a threshold mount, the CA3010-GE. The CA3010-FS anchor set is the standard snap together header type, so a full tube cut away header takes the CA3010-FK instead.
5) Will the Calibre CA3311 closer meet ADA opening force on our entrance?
The spring tension on the CA3311-S-DP is adjustable on site rather than fixed at the factory, so the closing force can be dialed to a range of force and code requirements after the closer is already installed. That is the practical difference from a fixed-size closer: if the door fails an opening force check at final inspection, you adjust the unit instead of swapping it.
6) Can the Calibre CA3311-S-DP be used on a fire rated storefront door?
It is UL10C Listed under positive pressure with no hold open, and also carries UBC 7.2 (1997) and BS476 fire safety. The no hold open part is not incidental: the CA3311 is a non-hold-open closer, which is what a fire door needs. A hold open version of this closer would not carry the same listing on that opening.
7) What is the difference between the Calibre CA3311 and the other CA3300 Series closers?
Back stop angle and hold open are what separate them. The CA3311-S-DP gives a 105 degree back stop with no hold open. The rest of the CA3310 Series covers 105 or 90 degree back stops with or without hold open, and the CA3301 through CA3303 models step up to a 130 degree back stop with various hold open options. Pick by how far the door needs to swing before it stops and whether the opening is allowed to hold open at all.
8) Do I need a separate overhead stop if I use the Calibre CA3311 concealed closer?
No. The 105 degree back stop is built into the closer, so the door is stopped at 105 degrees by the unit itself. Positive cam centering also holds the door secure against wind and pressure at the closed position, which matters on an exterior storefront entrance where a door can get pushed off center.
9) Can I slow the door down without it failing to latch on the Calibre CA3311?
Yes, closing and latching are on separate valves. Dual independent speed valves let you slow the main sweep for traffic while keeping enough latching speed at the end of the swing to pull the door into the latch. Both are field adjustable on the installed unit.
10) My door needs a longer closer spindle than standard. What do I order from Calibre?
The 3300-20 Series is the extended shaft version, with a spindle 17/64" longer than standard. Order that variant when the top rail or arm stack puts the arm out of reach of a standard CA3311 spindle. Same closer otherwise.
11) Can I get just the closer body to replace a failed Calibre CA3300 unit and keep the existing arm and pivot?
Yes. The CA3300-B is the unit body only, so an existing installation with sound arm, pivot and anchor hardware can take just the body. You have to specify spring tension, type and function when ordering the body on its own, since those live in the unit and not in the arm.
12) Will an overhead concealed closer work on a wood or hollow metal door, or is it only for aluminum storefront?
The CA3311-S-DP is built for aluminum storefront doors, and it mounts in the header pocket with a top arm sized to the door's top rail depth (1/2" through 1" depending on arm). A door with no closer pocket in the frame and no matching top rail prep is not a candidate for this unit. On that kind of opening you want a surface mounted closer instead.
13) Will the Calibre CA3311 hold up on an entrance door in a cold or hot climate?
The hydraulic fluid in the CA3311-S-DP is specified for stable performance across varied climates, so the closing speed does not swing as far with temperature as it would on a closer without it. That is the property that matters on an exterior entrance where the closer sees sub-freezing mornings and full sun afternoons on the same door.
