  • COMBO gives you an advantage over other builders when you're out there bidding for jobs
  • COMBO builders hardware is designed and manufactured by sliding door specialists who know your customer needs ... and your building requirements. That's why COMBO has so many exclusive, easy-mounting advantages that help your building crews hang sliding doors easier, faster and better. And, that adds up to more profits for you.



  • COMBO "Trundle Trolley" takes the "Struggle" out of hanging sliding doors. With the patented, COMBO Trundle Trolley, there's no need to round-up your entire crew to help hang sliding doors...even on sloping ground, in close quarters or windy conditions. Trundle Trolleys are simply rolled into the track and hanger bolts installed in the door leaf while still on the ground. The door leaf is, then, leaned against the building beneath the track and the Trundle Trolleys are rolled over to engage the hanger bolts. Final door height is adjusted with the locking nuts on the hanger bolts.
  • COMBO-hung doors are weather-tight!
    Choose standard track cover or exclusive COMBO "Snap-Up" cover. Either way, you can be sure that rain or snow can't enter the building. End caps and cover trim keeps birds out of the track, too!
  • COMBO track goes up easy and fast!
    No costly, on-the-job assembly. All mounting brackets are projection-welded (Projection-welding does not destroy the galvanized finish) to the track at 24-inch intervals. Whether you're using side-mount or top-mount COMBO track, you simply hold it up to the track plank and nail it quickly into place
  • "Snap-Up" Cover brackets speed installation!
    Exclusive COMBO "Snap-Up" cover brackets are conveniently out-of-the-way when you're mounting track and hanging doors. When you're ready to install the cover, snap quickly and firmly into place with just the tap of a hammer.
  • No fasteners needed with COMBO "Snap-Up" Cover!
    It goes up in a hurry...and it's there to stay. You simply hook the top lip of COMBO's unique "Snap-Up" cover behind the offset recesses at the top of the ot the track mounting brackets and push down on the cover brackets. For side-mounting applications, only. Standard cover is also available.
  • COMBO Track Eliminates Splicing!
    Save splicing time and costs by ordering COMBO track to fit your specific door widths. Comes in standard lengths from 8 to 20 feet in 2-Foot increments. Other lengths are available on request ...splice collars, too, if needed.
  • COMBO Assures Strong, Accurate Installations!
    COMBO track is roll-formed for maximum uniformity from strong, 14-gauge, galvanized, high-carbon steel. Projection-welded track mounting brackets assure perfect slot alignment throughout. Unique, flat-top track design imparts extra strength ...handles up to 600-pounds with two trolleys; up to 800-pound doors with four trolleys. Longer track lengths mean fewer joints for stronger installations and smoother-rolling doors.
  • COMBO Simplifies Inventory!
    No need to stock mounting brackets for COMBO track. They're all factory installed. And, you can eliminate splice collars, too, by ordering COMBO track in just the right lengths for your buildings. COMBO trolleys are also interchangeable with other round track trolleys.
