Designed specifically for timber sash windows, this fastener features a classic quadrant arm mechanism that draws the meeting rails tightly together, improving both security and draught resistance.

Crafted from high-quality materials and finished in a polished marine coating, it offers enhanced durability and resistance to corrosion—making it especially suitable for coastal environments or areas exposed to moisture. The smooth, reflective finish adds a refined touch, complementing both period properties and high-end contemporary interiors.

Finish

Our Polished Marine 316 Stainless Steel is a bright, high sheen, finish well suited to a range of architectural styles. A versatile choice that looks especially striking when used against dark and dramatic hues, but also works when paired with a range of more subtle colours for a classic look.

Manufactured with high concentrations of chromium and nickel, our Satin Marine Stainless Steel is grade 316 and offers extremely resilient, corrosion resistant properties, exceeding 1,000 hours salt testing. This finish is an excellent choice for coastal locations and highly polluted environments.

Care & Maintenance

An extremely hardwearing finish which offers exceptional protection against corrosion. Having surpassed 1,000 hours salt testing, it's an excellent choice for use in salt rich, or heavily polluted environments.

Despite the natural durability of this finish, we would still recommend washing your product using a soft, clean cloth and mild soapy water from time-to-time to reduce unnecessary pollutants building up on the products surface. Please ensure all products are dried immediately with a clean, soft cloth after any cleaning.

Over time, stainless steel can appear to tarnish. This is due to surface particulate deposits rather than the stainless steel itself. Specialist stainless steel cleaning products such as our 'Stainless Steel Cleaner Kit' K490 are available to remove tarnishing and nylon abrasive pads can aid in their use, being careful to use them in the direction of the grain.

Carbon steel wool is reactive and should never be used on stainless steel.

To increase the mechanical life expectancy of your products, we recommend regular oiling of all moving parts using ‘3-in-1 Oil’. This process is also highly recommended during initial installation.
