NGP C627DKB 36 – Frequently Asked Questions

1) What lengths does the NGP C627DKB brush door sweep come in, and can I cut it down to fit my door?
The C627DKB comes in 36, 38, 40, 42, 44, 48, 52, and 60 inch lengths, plus a 108 inch stock length. The 36 inch size covers a standard 3-0 door and the 108 inch piece is there for oversized openings or for cutting several doors out of one stick. The aluminum housing is 6063 T5 extrusion, so it cuts to length with a hacksaw or a chop saw and the nylon brush trims with shears. Order the next size up from your door width and cut down rather than trying to stretch a short piece.
2) How much gap under the door will a 9/16 inch nylon brush sweep close?
The brush projects 9/16 inch below the housing, so it is sized for the normal undercut you find on a commercial door, roughly a half inch of clearance. Mount the housing so the brush just kisses the floor with the door closed. The screw holes are slotted, which gives you vertical adjustment to dial the contact in after the first pass. If your door is undercut well past a half inch for return air or carpet, a 9/16 inch brush will not reach and you want a deeper brush or an automatic door bottom instead.
3) Should I use a nylon brush sweep or a rubber or vinyl door bottom sweep?
A brush sweep like the C627DKB is the one to use for sweeping debris, dust, and insects, and for doors that drag over carpet, uneven concrete, or a threshold, because the filaments flex over obstructions instead of catching and tearing. A solid insert sweep seals tighter against air and water but needs a flat, consistent surface to bear on. If your priority is weather sealing on a smooth exterior threshold, one of the neoprene or elastomeric insert sweeps such as the Cal-Royal BTN-112 or the Pemko 345V with its Eco-V insert is the better fit. For an interior or service door that has to sweep and survive traffic, take the brush.
4) What is the closest brush door sweep to the NGP C627DKB if a different brand is required?
The Pemko 29326NB is the nearest match in construction: it is a brush door bottom sweep on an aluminum housing, like the NGP C627DKB, and carries a clear anodized aluminum finish with a concealed fastener design in a 36 inch length. The NGP C627DKB uses a dark bronze aluminum housing with synthetic polyamide brush and mounts through slotted screw holes with the supplied #6 x 3/4 inch stainless screws, so the visible difference at the door is the exposed slotted fastener line and the bronze housing versus the anodized housing with fasteners concealed. For a locksmith or contractor matching brush action on a sweeping door bottom, both seal the same way; for a property manager matching an existing bronze hardware set on a fleet of doors, the finish is the deciding factor.
5) When should a neoprene or vinyl insert sweep be used instead of a nylon brush sweep like the NGP C627DKB?
Use a solid insert sweep when the opening needs a continuous contact seal against air and water rather than a debris and insect barrier. The Cal-Royal BTN-112 is a door bottom sweep built on an extruded aluminum retainer with a neoprene insert, and the Pemko 345V and Pemko 56 Series are door bottom sweeps carrying an Eco-V insert. Those wipe the threshold as a single flexible blade. The NGP C627DKB carries a 9/16 inch synthetic polyamide brush, which flexes over uneven floors, carpet transitions and thresholds without dragging and is the choice where the sill is irregular or the door has to swing over floor covering. On a smooth, level sill where the goal is a tight weather seal, the insert style is the better fit.
6) Will a rain drip door bottom substitute for the NGP C627DKB brush sweep?
No, they do different jobs at the door. The Pemko 3452 is a surface plate rain drip door bottom, which sheds water running down the face of the door away from the sill. The NGP C627DKB is a brush sweep that seals the gap between the door bottom and the floor against debris and insects. On an exterior opening a specifier often uses both, the drip above and the sweep at the bottom edge, so ordering the drip in place of the sweep leaves the floor gap open.
7) Will a nylon brush door sweep hold up on a boiler room or kitchen door where it gets hot?
Temperature is where this one separates itself. The synthetic polyamide brush and aluminum housing are rated from -70 F to 425 F, which covers mechanical rooms, boiler rooms, commercial kitchen back-of-house, and unconditioned loading docks in a hard winter. It is BHMA certified to ANSI/BHMA A156.22 including the heat and cold performance tests, so that range is a tested figure rather than a claim.
8) Do I need to buy screws separately for the NGP C627DKB door sweep?
No extra hardware needed. The sweep ships with #6 x 3/4 inch stainless steel sheet metal screws, and the holes in the housing are slotted so you can shift the sweep up or down before you snug them. On a hollow metal or wood door those screws go straight in. What is not included is a drill or a saw, so if you are cutting a longer piece to width you will want to re-drill or re-slot the cut end.
9) Is the dark bronze finish on this NGP sweep going to match my existing bronze door hardware?
The C627DKB housing is dark bronze finished aluminum, which is the standard match for dark bronze anodized storefront, bronze exit devices, and 613 or 10B door hardware. If your other openings carry a clear anodized or aluminum-finish sweep, this will read noticeably darker against them, and something like the Pemko 29326NB in clear anodized aluminum is the closer match for that case. For a property manager standardizing a building, pick one finish and run it on every door.
10) Can I use this NGP brush sweep on the outside of an exterior door for weather and rain?
A brush sweep is not a rain seal. The C627DKB is built for debris, dust, and insect control, and the brush will pass driven water and lose air infiltration performance against a solid insert. On an exterior opening that takes weather, pair the door bottom with a drip cap, or move to a rain drip bottom such as the Pemko 3452 surface plate rain drip. Where the door only sees light exposure and you mainly want to keep leaves and bugs out, the brush is fine.
11) For a healthcare or school project with indoor air quality requirements, is there an alternative to the NGP C627DKB?
The Pemko 345V is a door bottom sweep with a GREENGUARD Gold certified Eco-V insert, which is the certification institutional specifiers usually cite for low chemical emissions in occupied spaces such as classrooms and patient areas. The NGP C627DKB answers a different set of requirements: it is BHMA certified to ANSI/BHMA A156.22, rated from -70 F to 425 F, and REACH and RoHS compliant on materials. An MRO or institutional buyer working to an emissions credit should look at the 345V; one working to a gasketing performance standard or a wide temperature range stays with the C627DKB.
12) Which door sweep covers a door wider than a standard opening without splicing pieces together?
The NGP C627DKB is stocked in lengths up to 108 inches, so an oversized or double-egress leaf can be cut down from a single piece. Among the comparable brush and insert sweeps, the Pemko 29326NB and the Pemko 56 Series are each specified at 36 inches. For a contractor sealing a 42 inch or 48 inch leaf, the C627DKB also comes in 38, 40, 42, 44, 48, 52 and 60 inch lengths, which lets the job be ordered close to size and trimmed rather than pieced.
13) Is the Cal-Royal BTN-112 a direct replacement for the NGP C627DKB on the same door?
Not a like-for-like swap. Both mount to the face of the door on an aluminum carrier, but the Cal-Royal BTN-112 seals with a neoprene insert in an extruded aluminum retainer while the NGP C627DKB seals with a 9/16 inch synthetic polyamide brush. Swapping one for the other changes how the bottom edge behaves over the floor and changes the look of the seal line, so on a run of doors already carrying the C627DKB in dark bronze the replacement should stay with the brush profile to keep the fleet consistent.
14) Is this NGP door sweep rated for commercial use or is it a residential product?
Commercial grade. It is a commercial specification item, certified to ANSI/BHMA A156.22, and it goes on office buildings, schools, hospitals, retail, warehouses, multi-tenant residential, and government facilities. For an institutional buyer standardizing a facility, the A156.22 certification and the 6063 T5 aluminum housing are the two lines that matter on the submittal.
15) Are NGP brush door sweeps REACH and RoHS compliant for a green building spec?
Yes, the C627DKB materials are REACH and RoHS compliant, which covers most procurement screens on restricted substances. If your spec asks specifically for a GREENGUARD Gold certified component, that is a different program, and the Pemko 345V with the Eco-V insert is the item in that family carrying GREENGUARD Gold.
16) Will the nylon brush wear out or take a set on a high traffic door?
The filament is synthetic polyamide, chosen for abrasion resistance, flexibility, and memory retention, meaning the brush springs back rather than laying over permanently after the door sweeps across it a few thousand times. That memory retention is the reason a brush is used on doors that see constant cycling, and it is why the brush keeps closing the gap after the first season instead of leaving a flattened strip.
