Panel Construction
The industry leader in innovative door technology

Easy Replacement
This Speed-Master® door is constructed of patented, interlocking aluminum hinges creating a sectional panel design by connecting the 90 oz. / sq. yd. Bulldog XT panels for panel stability and wind resistance. Sliding apart the panels without removing the entire door assembly allows for inexpensive replacement. Since the bottom bar consists of fewer parts and does not support a tensioning system, it can be replaced at a lower cost than competitive products.
Product Features

Exterior Mount with Hoods and Motor / Gearbox Heater
Options such as hoods and motor / gearbox heater make it possible to install the Speed-Master® 4600 L on the building exterior so that high traffic door openings can be just as useful and efficient during inclement weather as they are during temperate times of the year.

Breakaway Bottom Bar Minimizes Downtime
Our breakaway bottom bar breaks away upon impact. The door may be quickly reset so the door is up and running with minimal downtime.

Light Curtain Protects and Saves on Maintenance Costs
Personnel and materials are protected by virtue of the standard light curtain. Positioned inside the low-profile guide tracks, light beams shine across the opening. If a beam is interrupted, the door automatically reverses. In addition to protecting pedestrians and materials from contact with the door, this system reduces the likelihood of damage to the door, which saves on maintenance costs and downtime. Ask about additional safety accessories available to enhance protection of pedestrians and vehicles: LED Lite Advance, advanced technology motion detectors, and more.

Available Upgrades
Consider these additional upgrades for your individual needs

Widescan Laser Sensor
The Widescan sensor uses laser technology, based on analysis of time of flight. It creates a volumetric area in front of the door opening by generating seven angled laser curtains, and it detects objects based on object size, height, speed, and direction. One device alone carries out three functions: opening the door, area surveillance and safety. More than just a sensor, it becomes a protective mechanism for the door and the user. The Widescan may also be programmed to function as a virtual pull cord. A mobile app is available to easily configure sensor settings from the ground.

Remote Keypad
Performs control box functions from ground level. More and more installations require that the door control box is installed out of the reach of passersby or completely away from the door in a central location. For these types of applications, our remote keypad is the ideal accessory. It allows for the actual door control box to be remotely installed while still having the ability to operate all control functions through a compact, 3” x 5-½” keypad at ground level.

LED Lite Advance
Designed to increase environmental awareness, the LED Lite Advance is bright LED light strips that are attached to the guide tracks or hood for an additional level of safety around the door opening. Easy to install on new or existing doors, lites are solid red when the door is down, flashing red when in motion, and solid green when completely open.

IS40 Motion + Presence Detection
Effectively accommodate motion and presence with the IS40. A rugged IP65 rated enclosure stands up to harsh environments, while bidirectional, unidirectional approach, and unidirectional depart microwave detection options help conserve energy. Six modes of detection filtering are available, as well as pedestrian and parallel traffic rejection.
Warning Lights
With and without horn
Warning Light
Our highly visible warning light provides a visual warning that the door is in motion, so traffic approaches the door with caution.
Warning Light with Horn
A warning light with a horn is an option for extremely busy locations where an added level of awareness is desired.

Custom Panel Imprints
Custom panel prints make a big impression. Logos, pictures, and text may be digitally printed onto our Speed-Master® and Speed-Commander™ door panels. The images are durable, UV treated and waterproof. Maximum image size is 7’0” wide x 3’0” high.
