Roller set with plastic diabolo electrolytically zinc-plated

Compact roller set with plastic diabolo for smooth, centred guidance of sliding elements in greenhouse structures. The bracket is made from sheet steel with an electrolytically zinc-plated finish for everyday corrosion protection, while the polymer diabolo (hourglass profile) keeps movement aligned on tubes, edges and guides without scuffing coatings. Low-profile geometry minimises projection into crop aisles.

Ideal for lightweight sliding doors and hatches, service panels, guide lines and screen accessories. The diabolo shape self-centres on the track and distributes load evenly, reducing point wear and rattle. The set installs quickly with standard screws/bolts; no welding required, easy to adjust during commissioning and seasonal maintenance.

Key features

• Plastic diabolo roller: self-centering, low-friction guidance; protects painted/galvanised surfaces.
• Electrolytically zinc-plated bracket: clean, uniform coating on sheet steel for greenhouse use.
• Low profile & quiet running: compact assembly reduces snagging and operating noise.
• Quick installation: bolt-on fitting with common fasteners; easy to re-position.
• Versatile use: sliding sections, guide wires, service frames and light screen hardware.

Typical greenhouse applications

• Guiding light sliding doors, vents and access panels.
• Routing of screen edges, cords and guide lines.
• Support/guide for service rails and frames along purlins and trusses.

Installation guidance

• Mount the bracket on a clean bearing surface; align the diabolo to the tube/edge and tighten fixings evenly.
• Do not over-torque; ensure the roller runs freely without side-load binding.
• Preserve the zinc finish; avoid grinding/cutting near the installed set.

Maintenance

• Periodically check for play, flat spots and fastener condition; re-torque if required.
• Keep the running surface clean to minimise abrasion and noise.
