Zero International 770AA36 – Frequently Asked Questions

1) Will the Zero 770AA gasketing still seal a door that has settled or a frame that keeps moving?
That is the reason to pick the 770AA over a fixed seal. Countersunk stainless steel adjusting screws drive the neoprene insert out by up to 0.310 inches (7.9 mm), so when a door sags or a frame shifts you reset the contact with a screwdriver instead of pulling the seal off and replacing it. Zero calls the arrangement the Compress-O-Matic system. The gasket itself is solid neoprene with neoprene sound dampening pads along the inner sidewalls of the case.
2) Does the Zero 770AA mount on the door stop, or does it act as the stop itself?
Either way. The 770AA can be installed as the door stop or applied onto an existing stop, and the fire seal rating follows that choice: 45 minutes used as a stop, 90 minutes when applied to a stop. The extruded aluminum case is stated at 1.25 inches plus 0.5 inches wide and 0.914 inches high, so measure the rabbet you have before deciding to face-mount it on an existing stop.
3) What lengths of Zero 770AA do I order for a standard 3-0 x 7-0 commercial door?
Two 84 inch pieces for the jambs and a 36 inch piece for the head covers a 3 foot by 7 foot opening. The 770AA comes in 36, 38, 42, 60, 80, 84 and 96 inch lengths, so taller or wider frames are covered by stepping up to the 96 inch length. Remember it takes three pieces per single opening, not one.
4) Is the Zero 770AA perimeter gasketing fire rated, and for how long?
Fire seal rated at 45 minutes when the gasketing serves as the stop, and 90 minutes when it is applied to an existing stop. Those two figures are not interchangeable, so if the opening is on a 90 minute label the 770AA has to go onto a stop rather than replace one. It is also rated as a smoke seal, an air seal and a sound seal.
5) Does the Zero 770AA seal the bottom of the door too, or just the perimeter?
Head and jambs only. The 770AA seals the three sides of the frame and does nothing about the gap under the door. A door bottom or sweep handles that edge, usually paired with a threshold, and both are ordered separately. If you are chasing smoke or noise through an opening, the undercut is normally the biggest single gap left once the perimeter is sealed.
6) What is the closest neoprene alternative to the Zero 770AA head and jamb gasketing?
The NGP 108NA is the nearest neoprene counterpart to the Zero 770AA. The 108NA is a neoprene sponge seal carried in an anodized aluminum frame, and it is rated for a temperature range of -20 F to 200 F. The Zero 770AA is a one-piece clear anodized extruded aluminum perimeter seal with a solid neoprene gasket and inner sidewall neoprene sound dampening pads, and its countersunk stainless steel adjusting screws provide up to 0.310 in (7.9 mm) of sealing adjustment after the door or frame moves. Both are aluminum-framed neoprene perimeter seals for head and jamb; the difference to settle before you order is sponge neoprene in a fixed frame versus solid neoprene set by adjusting screws, and whether the opening sees the temperature swing the 108NA is rated through.
7) Will the Zero 770AA help with noise coming around a hotel or office door?
It is sound seal rated, and the construction backs that up: solid neoprene against the door face plus neoprene sound dampening pads on the inner sidewalls of the aluminum case, so the extrusion is damped rather than acting as a hard channel. For guest rooms, exam rooms and conference doors the perimeter gap is where most of the flanking noise travels, and the adjusting screws let housekeeping or maintenance tighten the contact later when a door starts to sag. The undercut still needs its own seal.
8) Is the Zero 770AA suitable for an exterior commercial entrance?
Nothing in the assembly is bare steel. The case is clear anodized extruded aluminum, the gasket is solid neoprene, and the adjusting screws are countersunk stainless steel, so the fasteners that carry the adjustment will not seize with rust at an exterior head. Zero lists the 770AA as a commercial product, and it is rated as an air seal, which is the rating that matters for infiltration on an exterior opening.
9) What is a cheaper alternative to the Zero 770AA if I do not need the adjustable feature?
If the frames are true and you just need a perimeter seal, a fixed-insert channel does the job. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, and the NGP 155V is a vinyl perimeter seal in a mill aluminum frame. Neither carries the screw adjustment the 770AA has, which is what you give up: with a fixed seal, a door that later settles means pulling the seal and reworking it rather than turning a screw.
10) Magnetic seal or adjustable compression seal for a hollow metal frame?
They solve the same problem differently. The 770AA is a compression seal: a solid neoprene insert pushed against the door face by stainless steel screws, adjustable up to 0.310 inches, and it works on any door material. The NGP 159MA is a magnetic seal in anodized aluminum, supplied at 84 inches, and a magnetic seal only pulls closed against a ferrous door face, so it is a hollow metal answer and not a wood or aluminum one. Where a door is already sagging or the frame moves seasonally, the adjustable compression seal is the one you can re-tune on site.
11) Is there a vinyl-insert perimeter seal I can use instead of the Zero 770AA?
Two vinyl-insert perimeter seals sit alongside the Zero 770AA. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, and the NGP 155V is a vinyl perimeter seal in a mill aluminum frame. The Zero 770AA runs a solid neoprene gasket with inner sidewall sound dampening pads in a clear anodized extruded aluminum case, adjusted by countersunk stainless steel screws through 0.310 in (7.9 mm) of travel. The decision is the insert material and the frame finish: vinyl in an aluminum channel or a mill aluminum frame on the Cal-Royal and NGP parts, solid neoprene in a clear anodized case on the Zero.
12) The Zero 770AA is a compression gasket - what do I use if the opening needs a magnetic seal?
For a magnetic seal rather than a compression gasket, the NGP 159MA is a magnetic seal in an anodized aluminum housing, supplied at 84 in. The Zero 770AA seals by compression: a solid neoprene gasket in a clear anodized extruded aluminum case, projected into contact by countersunk stainless steel adjusting screws over 0.310 in (7.9 mm) of range, and it is rated as a fire seal for 45 min as a stop and 90 min applied to the stop, plus smoke, air, and sound seal rated. Confirm which sealing method the opening was specified for before substituting one for the other, since the two set against the door in different ways.
13) What perimeter seal should I use instead of the Zero 770AA on a high traffic door where the gasket keeps tearing?
Look at a brush seal. The NGP 602A is a nylon brush seal in an anodized aluminum housing, and a brush element wipes past the door edge rather than being squeezed by it, so it takes repeated slamming and cart traffic without the compression damage a solid gasket sees. What you trade away is the sealing performance of the 770AA, which is rated as a fire, smoke, air and sound seal. On a labeled or acoustically sensitive opening, stay with the compression seal.
14) Will the Zero 770AA match the aluminum trim already on my other door frames?
The 770AA case is clear anodized extruded aluminum, which is the standard satin silver finish that reads alongside aluminum storefront and anodized frame trim. If the seals already installed in the building are mill finish rather than anodized, they will look brighter and less uniform next to it; the NGP 155V vinyl perimeter seal, for example, is supplied in a mill aluminum frame. For a building being standardized one opening at a time, sticking with one of the two finishes across the doors is what keeps the openings looking alike.
15) Which perimeter seals have an anodized aluminum finish to match across a building?
If the frames on a property are already carrying anodized aluminum seal housings, the Zero 770AA is a clear anodized extruded aluminum case with a solid neoprene gasket, and among the comparable perimeter seals the NGP 108NA neoprene sponge seal, the NGP 159MA magnetic seal, and the NGP 602A nylon brush seal all use an anodized aluminum frame or housing. The NGP 155V vinyl perimeter seal uses a mill aluminum frame, which is the one to look at twice if the finish has to read the same down a run of doors.
16) Can I run the Zero 770AA on the stop, or should I pick a different perimeter seal for that detail?
The Zero 770AA can be applied as a door stop or applied to an existing door stop, and its fire seal rating follows that choice: 45 min as a stop, 90 min when applied to the stop. It seats in the jamb rabbet with countersunk stainless steel adjusting screws driven to set neoprene projection over a 0.310 in (7.9 mm) range. The comparable perimeter seals are configured around their own sealing elements - the Cal-Royal PG-601 as an aluminum channel with a vinyl insert, the NGP 155V as a vinyl seal in a mill aluminum frame, and the NGP 602A as a nylon brush in an anodized aluminum housing - so match the seal to the detail drawn on the frame elevation rather than swapping on profile appearance.
