TKO Doors now offers their XLT track design that fits within headroom as tight as 18 inches. This new design track overcomes the challenge of guiding the door along the ceiling by providing a double groove radius and horizontal track. A trolley system located above the door transmits lifting and lowering power, either with manual chain hoist or push button actuated operator. Doorways that have low headroom are typically in older facilities, in areas leading to dumpsters and locations with ceiling-mounted compressors or heaters.
