Four tracks, one stage - which curtain track actually suits your venue and the way you use it?

Tracks
Choosing a stage curtain track.
Erail, UniBeam, UniTrack or 2Way - the right track comes down to your venue's size, the weight it carries, and how the curtain moves. Here's how to match them.
Erail for small to mid venues, UniTrack for flexibility, UniBeam for heavy loads, 2Way for simple masking.
Start with span and height, add the load, then decide how the curtain moves.
Walkalong, corded or motorised is a separate call - and it shapes safety and performance flow.
The track is only half the story. How the curtain moves, and who moves it, is the other half.
Four tracks. One right fit.
TSA carries the Triple E track range, and four systems cover almost every stage: Erail, UniTrack, UniBeam and 2Way. They are not ranked best-to-worst - each is the right answer for a different venue and load. Choosing well means matching the track to the job, not buying the biggest one.
The cards below are the three you will reach for most; the table adds 2Way and lays them side by side. All working loads are quoted at a conservative 5:1 safety factor. For the full specs and motors, see the tracks and hardware range.
Erail
The go-to from a compact drama studio to a hall around 12 m wide and 7 m high. Quiet, quick to install, and the track most people picture when they think theatre track.
Best for
Small to mid-size venues, light to medium curtains.
Operation
Walkalong, corded or motorised.
Note
Reliability without over-engineering.
UniTrack
The versatile all-rounder for touring, or spaces that change between events. Suits temporary and permanent installs, with multiple cording methods and shared components with UniBeam.
Best for
Touring, flexible or permanent heavy-duty setups.
Operation
Corded or motorised.
Note
Shares parts with UniBeam for later upgrades.
UniBeam
The heaviest-duty track. Large drapes, LED walls or scenic flats that need to glide; handles heavy loads and works horizontally or vertically for unusual builds.
Best for
Wide stages (12 m+), heights over 7 m, scenery.
Load
Up to 385 kg per scenery carrier.
Note
Doubles as a scenery and performer-flying track.
| Track | Best for | Operation |
|---|---|---|
| Erail | Small to mid-size venues, light to medium curtains | Walkalong, corded or motorised |
| UniTrack | Touring, flexible or permanent heavy-duty setups | Corded or motorised |
| UniBeam | Wide stages, heavy scenery, LED walls, performer flying | Corded or motorised |
| 2Way | Perimeter drapes, studios, acoustic masking | Walkalong only |
Start with the span. Then the load.
Choosing a track is the same discipline as choosing any rigging: start with the numbers, not the brand. The span and height of the opening narrow the field straight away - a 6 m studio and a 16 m main house are not the same problem.
Then add the load. Light masking curtains sit comfortably on Erail or 2Way; heavy house curtains, scenery or LED walls need UniBeam's capacity. UniTrack covers the broad middle, and shares components with UniBeam if the venue grows into heavier loads later.
Last, decide how the curtain moves - walkalong, corded or motorised - because that shapes both the track choice and the day-to-day experience of using it. That is the next chapter.
Walkalong, corded or motorised.
How the curtain moves is a separate decision from the track profile, and it drives safety, performance flow and ease of use:
- Walkalong is hand-pulled. Curtains are walked along the track by hand - no cords, no motors. Quiet, clean and low-maintenance. Best for small stages, schools, studios, masking and blackout drapes, and anything set before the show rather than moved live.
- Corded runs from the wings. A rope-and-pulley moves the curtain from a fixed point side-stage, keeping the operator out of view. Best for house curtains, legs and travellers, and any space that needs controlled, cue-able movement with a professional edge.
- Motorised is cue-ready. An integrated drive unit, controlled by push-button pendant, DMX or show automation, moves drapes smoothly and repeatably. Best for large venues, main stages and touring shows, scenic reveals and heavy curtains, where timing and reliability are non-negotiable.
Each method suits a different track and a different way of working. Erail takes all three; 2Way is walkalong only; UniTrack and UniBeam are built for corded and motorised duty. Match the movement to the show, not just the curtain to the opening.
When the curtain carries the show.
Most venues are well served by Erail or UniTrack. The reason to step up to UniBeam is load: when the track has to carry large drapes, LED walls, scenic flats or a performer, the lighter profiles run out of capacity long before UniBeam does.
UniBeam handles up to 385 kg per scenery carrier, runs straight or curved, and works horizontally or vertically - so the same track that flies a house curtain can become a scenery track or a performer-flying line. That cross-over is where a curtain track stops being soft-goods hardware and starts being rigging.
When a track choice crosses into scenery, LED or performer loads, it stops being an off-the-shelf decision. That is where our engineers spec it against the actual load and the actual room.
One supplier for the whole range.
TSA is the exclusive Australian distributor of the Triple E range - Erail, UniTrack, UniBeam and 2Way, plus the SDrive and TDrive motors that power them. One supplier spans the whole need, from a school-budget motorised drape to a main-house heavy track.
Because we carry and install the full range, the advice is not steered toward whatever is in stock. We spec the track to the span, the load and the way you will use it - and because the systems share components, the venue can upgrade without starting over.
We've got the track. You've got the show.
