FAQs

Is this union compatible with 150mm walls?

No, this specific model (WC490UC-P) is designed for 200-250mm wall thicknesses. You would need the WC440UC-P model for smaller walls.

Does this require any special tools for installation?

Generally, it requires standard manual tools for positioning and securing; follow the specific instructions included with your overall coping system.

Can this be painted over?

The product comes with a high-quality factory-painted finish. If you need to color-match, ensure you use a paint suitable for aluminium surfaces.

How long is the union?

This unit is 310mm in length.

Is the material weather-resistant?

Yes, it is made from durable aluminium which is highly resistant to weather damage and corrosion.

Troubleshooting

Union does not sit flush against the coping

Verify the wall thickness is between 200-250mm and check for any debris or mortar residue on the wall top that may be obstructing the fit.

Visible gaps after installation

Ensure the coping sections are aligned correctly before sliding the union into position; adjust the positioning of the adjoining coping stones if necessary.

Pros and Cons

Pros

  • Ensures a watertight seal between coping sections
  • Professional painted finish matches standard installations
  • Constructed from durable, corrosion-resistant aluminium
  • Easy to integrate into existing coping systems

Cons

  • Only compatible with wall thicknesses of 200-250mm
  • Requires precise measurement of the wall width prior to ordering
  • Not suitable for retrofitting onto non-standard coping profiles

Setup, Compatibility & Care

Before installation, confirm that your wall width falls strictly within the 200-250mm range; installing on thinner or wider walls will compromise the fit and protection. Ensure all surfaces are clean and free of debris before placing the union. Use appropriate fixing methods as recommended by the broader coping system instructions to ensure a secure attachment. For care, perform a bi-annual inspection of the joints to ensure that the seals remain intact. Clean the painted surface with mild soap and water if dirt accumulates to maintain the finish and prevent long-term staining.
