Cal-Royal ADB-702 Automatic Door Bottom with Solid Vinyl Seal for Wood and Hollow Metal Doors

The Cal-Royal ADB-702 Automatic Door Bottom is engineered and tested for durability and reliable performance, providing an energy-efficient door sealing solution that restricts air, light, smoke, and insects from around the door opening. Constructed from extruded aluminum combined with a solid vinyl extrusion seal, this regular-duty automatic door bottom is designed for semi-mortised or surface-mounted applications and works with either wood or hollow metal doors. With a width of ¾" (18.3mm), a height of 1 13/16" (45.5mm), and a maximum drop of ¾" (19.1mm), the ADB-702 delivers a precise, efficient seal for commercial door openings.

Key Features

  • Compact Profile Dimensions: Width of ¾" (18.3mm) and height of 1 13/16" (45.5mm) allow for semi-mortised or surface-mounted installation on standard door constructions.
  • Maximum Drop Clearance: ¾" (19.1mm) maximum drop ensures a tight seal against the threshold while maintaining smooth door operation.
  • Heavy-Duty Extruded Aluminum Construction: Combined with a solid vinyl extrusion seal for long-term durability and an effective barrier against air, smoke, sound, and fire infiltration.
  • Wood and Hollow Metal Door Compatibility: Suitable for installation on either wood or hollow metal doors, offering flexible application across commercial door types.
  • Non-Handed, Reversible Design: Can be installed for either left- or right-hand door configurations without additional hardware.
  • Low Closing Force Operation: Slotted holes allow for adjustment while maintaining low closing force for ease of everyday use.
  • Regular-Duty Semi-Mortised or Surface-Mounted Application: Purpose-built for regular-duty commercial use where semi-mortised or surface mounting is required.
  • Installation Guidance: Maximum cut should not be closer than 1 ½" to the set screw to maintain proper seal function and structural integrity.

Cal-Royal ADB-703DV-36 – Frequently Asked Questions

1) Will the Cal-Royal ADB-702 automatic door bottom work on a hollow metal door, or is it wood only?
Either. The ADB-702 mounts on wood or hollow metal doors, which covers most commercial openings. The body is extruded aluminum with a solid vinyl seal extrusion, and it installs semi-mortised or surface mounted, so you are not committed to routing a pocket in a metal door if you would rather surface apply it.
2) What is the difference between the Cal-Royal ADB-702, ADB-703, and ADB-705?
Duty rating and mounting method. The ADB-702 is regular duty for semi-mortised application. The ADB-703 is light duty and mortised. The ADB-705 is regular duty and mortised. So if you are fully mortising into the door bottom on a high-traffic opening, the 705 is the one; the 702 is the pick when you want a semi-mortised install; the 703 suits lower-traffic doors where the pocket is fully mortised.
3) Should I use an automatic door bottom or a door sweep on my commercial door?
A sweep drags on the floor the whole time the door swings; an automatic door bottom like the Cal-Royal ADB-702 stays retracted and only drops when the door closes. That matters over carpet, over a threshold, or anywhere a dragging seal would wear out or add closing effort. The ADB-702 uses slotted holes so you can adjust the drop and keep closing force low. If the opening has a flat floor, no threshold, and you just want to block draft cheaply, a sweep such as the Pemko 345 Series with a rain drip is the simpler part. If the floor covering changes at the opening or you need the door to swing clean, the automatic bottom is the right tool.
4) The door cannot be surface mounted because the bottom rail has to stay clean. What automatic door bottom should I use?
Stay within the Cal-Royal ADB family and move to the ADB-705, which is the regular duty mortised version, or the ADB-703 for light duty mortised applications. Both are cut into the bottom of the door rather than applied to the face, so nothing shows on the door surface. The ADB-702 is the regular duty semi-mortised or surface-mounted arrangement. All three are offered in 36 inch and 48 inch lengths in mill finish aluminum with vinyl insert and dark bronze anodized aluminum with vinyl insert. If the opening has to accept a surface-mounted unit instead, the Pemko SA Series 36 inch is a surface mount automatic door bottom.
5) Do I need to order a left hand and right hand version of the ADB-702 automatic door bottom?
No. The ADB automatic door bottom is non-handed and reversible, so one part covers both left and right hand openings with no extra hardware. For a property manager standardizing across a building, that means one line item instead of two, and no wrong-hand returns.
6) Is there a surface mount automatic door bottom option if I do not want to mortise the door?
The Cal-Royal ADB-702 handles it, since it is built for semi-mortised or surface-mounted application. If you want a purpose-built surface mount unit instead, the Pemko SA Series surface mount automatic door bottom is that part, with a GREENGUARD Gold certified Eco-V insert, which is worth knowing if you are chasing indoor air quality credits on the job.
7) Will an automatic door bottom help with sound and smoke, or only drafts?
The ADB-702's solid vinyl seal drops against the threshold to restrict air, light, smoke, sound, and insects at the door bottom. That is why it shows up on office, school, healthcare, hotel, and multi-tenant residential openings where a bottom gap leaks noise between spaces. It seals the bottom edge only, so if you are treating a whole opening you still need the perimeter gasketing on the jambs and head.
8) We need a low-emitting product for a school project. Which door bottom carries that certification?
The Pemko SA Series 36 inch surface mount automatic door bottom uses a GREENGUARD Gold certified Eco-V insert, which is the seal material specifiers reach for on educational and healthcare projects where indoor air quality criteria are written into the submittal. It is an automatic door bottom, so it does the same job at the opening as the Cal-Royal ADB-702, which uses a solid vinyl extrusion seal in an extruded aluminum body and is rated for commercial use in schools, healthcare facilities, and government buildings.
9) What finishes does the Cal-Royal ADB-702 automatic door bottom come in?
Two: AV, mill finish aluminum with vinyl insert, and DV, dark bronze anodized aluminum with vinyl insert. Both are offered in 36 inch and 48 inch across the ADB-702, ADB-703, and ADB-705. Mill finish is the usual pick on hollow metal and painted openings; dark bronze anodized matches bronze storefront and dark wood doors without a field paint step.
