TT1 - The robust curtain track with non-jamming guide-roller run Save time through less overhead suspension Span widths of 2m and more are easily achievable with the TT1 curtain track. You will need less than half as many attachment points as comparable tracks and will save valuable time as a result. Always on the roll Do you dislike grinding noise and loss of energy through friction as much as we do? In that case the TT1 curtain track with its 15kg payload runners (legally protected design) is the right solution! Are you still greasing or already rolling free? All pulleys and cable guide-rollers are made from a self-lubricating high-chem plastic. You can rest assured that they require no maintenance and will always run smoothly. Greasing was yesterday – today belongs to maintenance-free high-chem plastic!
