Hager 770SV 36 MIL – Frequently Asked Questions

1) Will the Hager 770S door sweep fit a 36 inch commercial door?
The 770S is sold in a 36 inch length, which covers a standard 3-0 commercial door leaf with no cutting. On a narrower opening the aluminum retainer is cut down to the door width before mounting. It's a commercial-rated sweep, so it's meant for entry and exterior leaves in office, school, healthcare, retail and multi-tenant buildings rather than light interior residential use.
2) Is the Hager 770S sweep UL Listed for a fire rated door?
Yes, the 770S carries a UL Listed fire rating, so it can go on a fire-rated door assembly. That is the spec an institutional or MRO buyer needs before hanging anything on a rated opening, and it is stated for this sweep rather than inferred.
3) Should I order the nylon brush or the vinyl insert on the Hager 770S?
Two insert codes are offered: V for the vinyl blade and B for nylon brush. Vinyl gives a tighter seal against a flat, even threshold and is the better choice for weather and air infiltration. Brush rides over an uneven or carpeted floor and over threshold plates without dragging, and it drags less on the door closer. Where a leaf has a wide or inconsistent undercut, the brush is more forgiving; where the bottom clearance is consistent, vinyl seals better.
4) What size is the vinyl insert on the Hager 770S sweep?
The vinyl insert measures 7/8 inch by 19/32 inch (22 mm by 15 mm). That 7/8 inch dimension is what tells you whether it will close your undercut: it needs a gap under the leaf small enough for the insert to make contact with the threshold but not so tight that the door binds. Measure the gap at the closed position, at both the hinge and lock edge, before ordering.
5) Does a door bottom sweep like the Hager 770S replace a door bottom or a threshold?
Neither, they are three different parts and a lot of orders go wrong here. The 770S is a surface sweep, it screws onto the face of the door near the bottom and its insert drags on the floor or threshold. An automatic or mortised door bottom sits inside or under the leaf and retracts. A threshold is the extruded piece fastened to the floor in the opening. The sweep is the retrofit part, it goes on an existing hung door with no machining and no floor work, which is why it is the usual fix when an existing opening starts leaking air or water.
6) What is the rain drip on the Hager 770S sweep for, and do I need one?
The rain drip is a projecting lip built into the sweep body that catches water running down the face of the door and throws it clear of the threshold instead of letting it track under the door. That matters on an exterior out-swinging leaf with no overhead protection. On an interior door, or a leaf under a deep canopy, a plain sweep without the drip does the same sealing job with less projection off the door face.
7) Do screws come with the Hager 770S sweep or do I supply my own?
Fasteners are furnished: #6 x 5/8 inch pan head sheet metal screws, plated to match the finish you order. Nothing else is needed to hang it on a hollow metal or wood leaf beyond a drill and the right pilot bit. One thing worth knowing on the finish match, mill finish sweeps ship with zinc plated screws rather than a mill plating.
8) Can I use the Hager 770S on a pair of doors or a double door opening?
Yes, sweeps are per leaf, so a pair takes two. Order one 36 inch piece for each leaf of a standard 6-0 pair and cut to the actual leaf width. The sweep only seals the bottom of each leaf, it does nothing for the gap where the two leaves meet, that gap is closed by an astragal, which is a separate part.
9) Can the Hager 770S be adjusted after it is installed if the door drags?
Yes. The sweep is fastened through slots with the #6 x 5/8 inch pan head screws, so it is set once the door is hung, then raised or lowered to get insert contact on the threshold without loading up the closer. Standard practice is to test the full swing after tightening, since a sweep set too low will fight the closer and wear the insert out fast. Hager publishes weatherstripping installation instructions for the exact sequence.
