Pemko 2891APK 36 – Frequently Asked Questions

1) Will Pemko 2891 gasketing clear a parallel arm door closer bracket at the head?
That is exactly what the 2891 head section is built for. It is the head piece of the perimeter gasketing run, shaped so a parallel arm closer bracket or other hardware mounted at the head has room, while the insert still seals against the door face. On the jambs you run the matching perimeter sections; the 2891 handles the top of the frame where the closer bracket lands.
2) Can I use Pemko 2891 gasketing on a fire rated door assembly?
Yes. The 2891 carries a UL 10C positive pressure fire rating and is smoke tested to UL 1784 for air leakage, with BHMA certification and Intertek (Warnock Hersey) testing. That combination is what an inspector looks for on a rated opening with a smoke requirement. It is also GREENGUARD Gold Certified, which matters on schools and healthcare projects with indoor air quality specs.
3) What is the difference between the PemkoPrene, silicone, and Eco-V inserts on the 2891?
Same aluminum retainer, different sealing material. PemkoPrene (2891_PK) is the general purpose commercial insert. Silicone (2891_S) is the one to pick where the gasket sees heat, temperature swings, or repeated wipe downs with cleaning fluids and disinfectants, which is why it gets specified in hospitals and labs. Eco-V (2891_V) is the option for projects chasing environmental criteria. All three inserts compress well and are self extinguishing and non toxic.
4) How much space does Pemko 2891 perimeter gasketing take up on the frame?
The 2891 has a 1/4 inch overall height and a 1 1/2 inch profile height. Check that against the frame face you have available at the head, particularly where a closer bracket, a hinge reinforcement, or an electric strike box is already occupying the stop face. If the run clears those, the gasket surface mounts to the frame with the supplied screws.
5) Should I use adhesive backed foam weatherstrip or an aluminum retainer gasket like the Pemko 2891 on a commercial door?
Aluminum retainer gasketing is the choice on any opening with traffic or a rating. Adhesive foam peels, takes a set, and has no rating behind it. The 2891 uses an aluminum base with a mechanically fastened, replaceable insert, so when the seal wears out years later you change the insert rather than the whole run. It is a commercial product and it is the type that carries the UL 10C and UL 1784 test results a rated or smoke rated opening needs.
6) Will the Pemko 2891 hold up to daily disinfectant wipe downs in a hospital?
The insert materials resist cleaning fluids and disinfectants, which is the reason this gasketing gets specified into healthcare and institutional work. The silicone insert is the one to hold out for in those areas. The insert is also self extinguishing and non toxic, and the assembly is GREENGUARD Gold Certified, so it fits patient care and classroom air quality requirements.
7) Can I standardize one gasket across every door in my building with the Pemko 2891?
For the head, yes, and that is the point of it. The 2891 covers openings from a 2 inch piece up to 185 inches, in one profile and one finish, so a facility can run the same head detail across offices, classrooms, back of house, and rated stair doors. Pick one insert material for the whole property and your maintenance stock is a single item. Where an opening has a parallel arm closer, the 2891 already accounts for the bracket, so the rated doors do not need a different part than the rest.
8) What finish does Pemko 2891 gasketing come in?
Mill finish aluminum, across every insert and length combination. That is the raw, uncoated aluminum look. If the frames on the rest of the building are painted or anodized dark, the head run will read lighter than the frame, so it is worth deciding up front whether that matters on a visible lobby opening or whether you are only gasketing back of house doors.
