Threaded Rod Mounting System

Using the Threaded Rod Mounting System to suspend your curtains will allow you to work around obstructions below your ceiling structure and your building’s sloped roof line. All connectors or split supports need a mounting point above as a truss, beam, or unistrut to support from.

The Threaded Rod Mounting Bracket
is the most used industrial curtain track hardware for two reasons. First, it allows you to level the track off of your existing structure if it is sloped. Second, you can bypass obstructions and hang the curtains and track below
  • Allows you to level the Track
  • Bypass obstructions
  • 16 gauge galvanized Steel for industrial use
  • The Threaded Rod System connects to vertical threaded rod. The top end of the threaded rod attaches to the structure via:
    • Beam Clamps
    • Ceiling Plates
    • Unistrut
  • The track can be mounted parallel or perpendicular to you existing members

About Track Sections

retractable straight track

Straight Track Sections are available in:

2′, 4′, 5′, 6′, 7′ and 8′ sections.

We do not recommend using tracks over 8′ long, as this drives shipping costs up. Since the track hardware is a heavier product, we want to ensure that the way we package the product has the least possibility of getting damaged in transit. All of our packing and handling is performed with the utmost care and attention to detail.

Threaded Rod Mount Curved Track
Curved Track 90° or 45°
  • Welded plain connectors on each end
  • Requires two beam flange split supports on each end of the curve
How to get around:
We offer 90 and 45 degree track curves. The 90 degree curve makes up 2ft. (on each side) of your required track width. The 45 degree curve makes up 10.5″ (on each side) of your required track width.

As seen on the images, the curves come with plain connectors welded onto each side. This allows for the next track section to fit into the curved piece seamlessly. Next to each curve end you must place a split support to support the track from above.

The curves can be used to create an L-shape, U-shape, 4-sided, or more custom track configuration. Additionally, the curved tracks allow the curtains to travel around them and move anywhere in the track layout.

About Connectors and Split Supports

Threaded Rod Corner connector

90 Degree Corner Connector

Another way to handle a corner within the track layout
would be to use a 90 degree corner connector. These pieces form a hard corner, which curtains cannot move around. Each piece comes with two set screws to secure the track sections on each side.

Threaded Rod T-Connector


The T-Connectors are used to create a divider in a rectangular track configuration. These are often used in the Auto Industry to create bays for painting or mechanical work on cars and trucks.

Threaded Rod Connector


Plain Connector with Threaded Rod Split Support

All connectors and/or Split Supports need a mounting point above; such as a truss, beam or unistrut to support from. The track run needs to be supported every 5 to 6 feet depending on the height (weight)of the curtain. For heavier curtains, such as our double barrier acoustic curtains, we recommend placing a support up to every 2′ in the areas where curtains are retracted too and stacked/stored.
If you are able to run your track parallel to and directly under a truss, then you would use the Threaded Rod Connectors. Because you are mounting to a continuous structure, you can place the connectors (and thus the clamps and/or mount plates with the Threaded Rod) anywhere along that structural member.

If you are planning on running the track perpendicular to your trusses and you do not know the distance between the trusses, we recommend using the plain connectors to connect the track. The split supports will need to line up under your ceiling structure so it is important to make sure that you have at least 6″ of space between the track joint (plain connector) and your split support. Split supports cannot be placed over/on top of a plain connector.

Split supports can be placed anywhere along the track, but not over a connector. Best placed next to or not to far from a plain connector.

Special Feature about the Threaded Rod Mounting Bracket

Reasons to suspend the track

Most buildings have a sloped roof for drainage purposes. Since the track has to be level in order for the curtain to slide back and forth, the track would have to be leveled by suspending the track with threaded rod.
Threaded Rod Level Track on Slope
Most building have obstructions that block a continuous track. It is best to suspend the track with threaded rod below the obstructions to allow for uninterrupted maneuvering of the curtains.

Suspending the track from a SLOPED existing structure.

Suspended from a sloped structure, directly below and parallel to the beams or trusses.

Threaded Rod Parellel Sloped
The beam clamp gets mounted to the bottom of the truss. The beam clamp has two 3/8″ -16 threaded holes. Since you have a sloped structure to mount to you will also need a Side Plate and bolt to make it possible for the threaded rod to hang straight down vertically. The side plate gets bolted into the side hole on the threaded rod clamp.

Suspended from a sloped structure, perpendicular to the beams or trusses.

If you suspend the track perpendicular to the trusses we recommend to use Swivel Clamps to make sure the threaded rod hangs straight down vertically.

Suspending the track from a LEVELED existing structure.

Suspended from a leveled structure, directly below parallel to the beams or trusses.

Threaded Rod Mount Level

The Beam clamp gets mounted to the bottom of the truss. The beam clamp has two 3/8″ -16 threaded holes. The threaded rod gets screwed into the bottom hole of the threaded rod clamp.

Suspended from a leveled, flat ceiling.

Threaded Rod Ceiling Mount
The Ceiling plate gets fastened with two anchor screws to the ceiling. Please make sure your anchors / fasteners can hold the weight. Since every ceiling is different the installers will provide the fasteners going into the ceiling.

Suspended from a leveled structure parallel between the trusses.

Some times it is not possible to hang along the trusses. you have to place unistrut every 5 -6 ft. perpendicular to your trusses. As shown at the image we recommend the U-Bolts to secure the unistrut onto the trusses. Now you have a structure to suspend your track parallel between your structure.

About End Stops and supporting the ends of the track

Wall Mount End Stops, Flange Up and Down
If you are able to run the track all the way to a wall you can use the Wall Mount End Stops to support the track end. Using these pieces provides more stability to your track overall. You would have to let us know if you prefer the flange to be UP or Down.

Another way to support the track end is to use a Split Support

If you use an Split Support to support your track end and your track does not stop at a wall you need to insert an adjustable end stop into the track end to make sure the trolley hooks don’t fall out.
An additional way to use the adjustable end stop is if you want to fixate one end of the curtain at a certain position.
Threaded Rod Mount End Stop
For example next to a wall so one of the curtain edges would be stationary. All you would do is using an additional adjustable end stop between the last two trolley hooks.

Trolley Rollers get slide into the Track and hooked onto the Curtains

Nylon Rollers

Used for ourSingle layer Curtain Products and for other lighter weight Curtains

Steel Roller

Used for our heavier type of curtains, such as Insulated and Acoustic.

Pull Rope Trolley

Overlap Trolleys are used on one of the curtains where you want to create an overlap. Ideal for pass-throughs.

Overlap Trolley

Used in a Industrial setting were the curtains get moved a lot.

It is important, and this is also explained in our Installation instructions, you would count the rollers needed per track run. By counting the Grommets on the curtains you will know the needed Roller amount. You must slide the roller into the track before mounting the last piece of track to the wall.
