Clamp ring 42 mm electrolytically zinc-plated

Compact clamp ring for 42 mm round tube (fits typical 42.0–42.4 mm OD). Formed from sheet steel with an electrolytically zinc-plated finish, it serves as a quick, re-positionable stop or locating collar on greenhouse frames and service rails. The low-profile body keeps aisles clear while preventing brackets, trolleys or guides from creeping along the tube.

Ideal as a positional stop for screen hardware, cable trays, irrigation lines and light fixtures. The ring seats firmly on the tube and tightens with a simple screw/bolt fastening (no welding), allowing precise setting during installation and easy adjustment during maintenance or seasonal reconfiguration.

Key features

• 42 mm clamp diameter: for standard greenhouse tubes (≈42–42.4 mm OD).
• Sheet steel, electrolytically zinc-plated: clean, uniform corrosion protection.
• Low profile stop collar: neat end-stop or positioner for moving parts on rails.
• Fast, non-weld fit: simple clamp fastening; easy to set and re-position.
• Greenhouse ready: use on trusses, purlins, door frames and service lines.

Typical applications

• End-stop and locator for screen systems and edge guides.
• Positioning of irrigation/cable trays and light brackets.
• Travel limits for trolleys or rollers on round rails.

Installation guidance

• Place the ring at the desired position on a clean tube; tighten the fastening evenly.
• Avoid over-torque on thin-wall tube; re-check after initial load/thermal cycles.
• Preserve the zinc finish; do not grind or cut near the installed ring.
