Norton Rixson F5314-NBC-LH-612 – Frequently Asked Questions

1) Will the Norton Rixson F53 floor closer handle a 250 lb interior door?
250 lbs is exactly the rated door weight for the F53 Series, and it's sized for doors up to 4 feet wide with a 90 degree maximum swing. It's a standard duty, moderate traffic closer for interior openings, so a heavy exterior entrance under constant public traffic is not the application. If your leaf is wider than 4 feet or heavier than 250 lbs, you need a heavier floor closer, not this one.
2) What is a shallow depth floor closer and why would I use one on an upper floor?
A shallow depth floor closer needs far less penetration into the floor slab than a conventional full depth unit, which is what makes the F53 usable on upper levels of a multi-story building where you cannot cut deep into a structural deck. It's an independently hung design, meaning the closer controls the door but the door's weight is carried on its own pivots rather than on the closer spindle. That is the trade: less floor depth and a 250 lb capacity, rather than the heavier capacity a full depth center hung unit gives you at ground level.
3) Do I have to specify hand when ordering the F53 floor closer?
Handing matters here. The F53 is a single acting, handed closer, so it's ordered left hand or right hand and swings one direction only. Stand outside the opening, on the side the door swings away from, and the side the hinges or pivots are on gives you the hand. Order the wrong hand and the unit will not work on the opening. If you need the door to swing both ways, this is not the closer for that.
4) Is the Norton Rixson F53 fire rated?
The F53 carries UL listing for 3-hour fire door assemblies. That covers it for fire rated interior openings in commercial office, healthcare, and educational construction. Note that a fire rated opening generally rules out a hold open arm unless the hold open is released by the fire alarm system, so match the arm function to what the opening's fire rating allows.
5) Can I get the F53 floor closer with hold open?
Arm function is an ordering choice on the F53: automatic hold open or non-hold open. Automatic hold open catches the door at the open position and holds it there until it's pushed shut; non-hold open lets the door close every time. The F5303NBC model is the non-hold open, backcheck configuration. On a fire rated opening, specify non-hold open unless the hold open is tied into alarm release.
6) What does backcheck do on a floor closer, and do I need it?
Backcheck cushions the door near the end of its opening swing so it can't be thrown open hard into an adjacent wall or the stop. On the F53 it's a separate independent valve, alongside independent valves for closing speed and latch speed, so you tune the three behaviours without one adjustment fighting another. In a corridor, a classroom, or anywhere wind or a pushed cart can slam the leaf open, backcheck is what protects the door and the closer.
7) Which door width option do I pick for the F53 closer?
Door width is ordered as 36, 42, or 48 inches, and the top of that range is the limit: the F53 covers doors up to 4 feet wide. Pick the option that matches the actual leaf width, not the frame opening. A leaf wider than 48 inches is outside this closer's range regardless of how much it weighs.
8) Will the F53 work on a pocket door application?
For a 90 degree pocket door installation, where the closer sits inside the pocket, the F5310 is the configuration to use, and it works with F519 pocket pivots. The standard F53 mounts parallel to the frame in a conventional opening. Two different applications, so match the model to which one you have.
9) Is the F53 an offset hung or center hung floor closer?
Offset hung is the F53's configuration, with the closer mounted parallel to the frame. That matters for door prep: an offset hung door pivots on a point set in from the edge rather than on the centerline of the leaf, so it is not a drop-in for a center hung opening. Check what the existing prep in the floor is before ordering.
10) Can the spring power on the F53 floor closer be adjusted for a heavier door?
Spring size is fixed on the F53, not field adjustable. You tune the door with the closing speed, latch speed, and backcheck valves, but the closing force itself is what it is. Size the closer to the opening up front, since a door at the heavy end of the range can't be compensated for by cranking up spring power after installation.
11) Can I match the F53 floor closer arm to the other hardware finishes in my building?
Thirteen finishes are offered across the standard BHMA range: 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. For a standardized commercial building, 626 satin chrome and 630-family satin finishes are the usual match to existing lever and closer hardware.
12) Does the F53 floor closer have delayed action closing?
Delay function is included on the F53. That slows the first part of the closing swing so someone with a cart, a wheelchair, or full hands has time to clear the opening before the door starts moving at normal speed. Closing speed, latch speed, and backcheck adjust independently of it.
13) Will the F53 closer case rust in a concrete floor?
The cement case is a rust-proof Cycolac cover, which is what sits in contact with the floor pour. It's specified for commercial interior openings, so it is not the choice for an exterior entrance exposed to weather and de-icing salt.
