Cal-Royal ADB-705D-36 – Frequently Asked Questions

1) Will the ADB-705 work on a hollow metal door, or is it only for wood?
Both. The ADB-705 is rated for wood or hollow metal doors. On hollow metal you're mortising into the bottom channel, on wood you're routing the door edge; the housing and mounting are the same either way, and slotted mounting holes let you shift the unit for height adjustment after it's in.
2) Do I have to order a left hand or right hand version of the ADB-705?
No handing to specify. The ADB-705 is non-handed and fully reversible, so the same unit installs on a left hand or right hand door. You only pick length and finish.
3) Is an automatic door bottom better than a plain door sweep for sealing a commercial opening?
They solve different problems. An automatic door bottom like the ADB-705 drops the seal only when the door closes and lifts it clear when the door swings, so there's no drag on carpet or uneven floor and the seal stays intact over time. A fixed sweep such as the Pemko 345 Series with a rain drip rides the floor constantly, which is simpler and cheaper but wears faster on traffic doors, though the rain drip makes it the better answer on an exterior door taking weather.
4) Will the ADB-705 make the door harder to close on an office or classroom opening?
It's built as a low closing force design, so the plunger retracts with light pressure rather than fighting the closer. That matters on interior commercial doors in offices, schools, and healthcare where closer force is already dialed down. It is a Regular Duty unit, so for very high cycle exterior or main entry openings a heavy duty automatic door bottom is the more appropriate specification.
5) What does the ADB-705 actually seal against?
The vinyl insert seals the gap at the base of the door against air, smoke, sound, and fire once the unit drops. In practice that means it's doing double duty on a corridor door: stopping the draft and noise transfer day to day, and closing the undercut on a smoke or fire opening. The aluminum extrusion carries the mechanism, the vinyl does the sealing and is the wear part.
6) Which door bottom should I use on an exterior door that gets rain?
Consider the Pemko 345 Series 36 inch door bottom sweep, which is supplied with an integral rain drip and a PemkoPrene insert to shed water away from the door bottom. The Cal-Royal ADB-705 is an automatic door bottom for mortised application with a vinyl seal that blocks air, smoke, sound and fire at the base of the door, and it has no rain drip component. Interiors, corridors and smoke or sound rated openings are where the ADB-705 is typically applied.
7) For a LEED or low emitting materials specification, is the Cal-Royal ADB-705 the right automatic door bottom?
For projects that require documented low emitting material credit, the Pemko SA Series 36 inch surface mount automatic door bottom uses a GREENGUARD Gold certified Eco-V insert. The Cal-Royal ADB-705 uses a vinyl seal in an extruded aluminum body and is a regular duty unit for mortised application, reversible for left or right hand doors and suitable for wood or hollow metal. If the sealing function is what matters and no certification is called out, the ADB-705 covers the mortised condition the SA Series does not.
8) What finishes does the Cal-Royal ADB-705 come in?
Two: AV, mill finish aluminum with a vinyl insert, and DV, dark bronze anodized aluminum with a vinyl insert. Both are offered in 36 inch and 48 inch lengths. Since the unit is mortised, only the face edge shows, so mill finish is the usual pick on painted or aluminum openings and dark bronze on bronze or dark anodized door lines.
