For buildings where the roof slopes and level horizontal track will not fit. The door rises through the high lift, then the horizontal runs at the roof pitch. Built in 304 stainless for wash bays, ag buildings, and salt sheds under pitched roofs.
High lift with pitch, sometimes called follow-the-roof or incline track, starts like high lift: vertical track extends above the opening for the lift amount, then the radius. The difference is the horizontal track, which is set at an angle to match the roof pitch instead of running level.
That angle changes everything downstream. Cable take-up, drum selection, spring sizing, and hanger geometry all depend on the pitch. We build from two numbers, the roof pitch (rise over run, or degrees) and the high-lift amount, so those matter more than anything else on the quote.
Pitched horizontals are common in pre-engineered metal buildings, ag structures, salt and sand storage, and wash tunnels built under a sloped roof.
Pitch plus lift sets the geometry. Everything else follows from the door size and weight.
Extended vertical, radius, then horizontal track angled to the roof pitch. The most common build, for buildings with a few feet of headroom before the roof starts to come down.
Best for: Most pitched-roof buildings
The vertical turns almost directly into inclined track with little or no high lift, for low-eave buildings where the roof comes down close to the header.
Best for: Low-eave metal and ag buildings
Bolted vertical sections with a high-lift head plate, so damaged track can be replaced in sections and the assembly can be installed around obstructions.
Best for: Doors that take hits, and tight installs
2-inch for lighter commercial doors, 3-inch for tall or heavy doors and high-cycle openings.
Best for: 3-inch on doors above about 14 feet or heavy panels
A level held against the underside of the roof structure and a tape give us rise over run. A photo of the truss or purlin with the level in it is ideal.
Not sure how to measure? The Track ID Guide shows where each dimension is taken. Photos of the opening from inside help more than anything else.
Hold a level against the underside of the roof structure and measure how much it rises over a 12-inch run. Four inches over twelve is a 4:12 pitch. Degrees work too. If you are unsure, send a photo of the truss or purlin with a level against it.
Yes. A pitched horizontal changes how cable takes up as the door travels, so drums and springs are sized to the pitch and the lift. That is why we ask for a measured pitch rather than an estimate.
Sometimes, by building the horizontal in straight segments. Send the roof profile and photos and we will tell you whether pitched track or a different configuration is the right answer.
Long sections ship LTL freight, curbside, and may need an appointment. Shorter runs and hardware ship UPS. The quote states the shipping method, the lead time, and whether a liftgate is needed.
