In-the-Floor Kits

For use with Horton Automatics series 4100 Side Load Operators

In-the-Floor Kits (4440-S)

Our 4440-S Standard Series is designed to perform with the installation of NEW O.E.M. automatic door operators and controls as supplied by the specified manufacture and/or distributor. This product is not designed for the use and conversion of existing, previously installed, remanufactured or rebuilt overhead automatic door operators. The 4440-S “Standard Series” mounts within the floor, directly below the door and acts as the lower portion door pivot, closer and operator. Our design is of the highest quality. We manufacture fully welded housings in order to maintain and assure a complete seal while embedded in concrete. We utilize 1/8 hp motor/gearboxes. All internal components are machined and welded. Our Standard products are manufactured with a 1” shaft. We use two sealed shaft flange bearings and one shaft thrust bearing, a total of three bearings, allowing our 4440-S “Standard Series” to support doors weighing up to 1500 lbs. Though our seals are the best in the industry, we insist for safety as well as quality assurance that all electronic controls be mounted in our remotely located UL listed NEMA 1 control box. After manufacturing for nearly thirty years, we understand problems that moisture, condensation and water vapor can and will bring to delicate electronics that are mounted in a bed of concrete. Remote above ground location also allows speed, check and reversing adjustments to the door operator without the need to pull up thresholds. For safety, it maintains all 110vac above the ground.
