Pipe clamp Marmat UZ20 closed for smooth PVC pipes Ø20 mm, white

Marmat UZ20 closed pipe clamp is designed for secure mounting of smooth PVC pipes with a nominal diameter of 20 mm. The white finish integrates with indoor installations and provides a discreet fixture for plumbing, drainage, conduit routing and light HVAC lines. The clamp is constructed to hold the pipe firmly in position, reduce movement and damp vibrations while enabling straightforward installation by snap or screw fixing.

Advantages

The closed design fully surrounds the pipe for consistent support and protection from lateral displacement. Its white surface is suitable for visible indoor installations and resists discoloration under normal indoor conditions. The clamp allows installation by either snapping the pipe in place where applicable or using a screw through the mounting hole for a more permanent attachment, delivering a combination of ease of use and reliable retention.

Suitable for

• Mounting smooth PVC pipes with outer diameter 20 mm in residential plumbing
• Securing drainage lines and condensate tubes
• Routing electrical conduits and cable protection tubes in interior spaces
• Light HVAC lines and small-diameter ventilation ducts

Key specifications

• Compatible pipe outer diameter: 20 mm (nominal)
• Design: closed clamp providing 360° pipe support
• Color: white for indoor integration
• Mounting options: snap-fit or screw attachment via mounting hole
• Material: durable polymer suitable for plumbing and conduit use

How to use

Select the clamp location along the run of PVC pipe and ensure the substrate is suitable for screw fixing if a mechanical attachment is required. For snap-fit installation, align the pipe with the clamp opening and press until the pipe seats securely inside the closed profile. For screw fixing, position the clamp, mark and drill a pilot hole if needed, then secure the clamp to the mounting surface with an appropriate screw. Space clamps at regular intervals to prevent sagging and to maintain line alignment.

Usage recommendations

Use clamps at manufacturer-recommended intervals for the specific pipe type and application; avoid over-tightening screws to prevent deformation of the polymer body. For external or chemically aggressive environments, select clamps with materials rated for those conditions. Regularly inspect mounted runs for movement or wear and replace clamps if cracking or significant deformation is observed.
