70mm uPVC Window Frame H Coupling (Choice of colour and length) Protect and seal straight frame joints! Durable PVC-u, window and door frame coupler, for maintaining alignment, spacing, and weather-tightness between 70mm frames. Its narrow profile means frames can fit tightly together to maximise glazing, whilst its H-profile conceals the joint and creates a neat professional finish, inside and out. Manufactured sustainably, using the same recycled material and colour-fast foils as window and door frames, to offer the same long life expectancy. Slimline frame-to-frame couplers are often used on the joint between a door and a flag frame window, between conservatory doors and windows over a dwarf wall, and between inline frames on long window span. Features & Benefits Neat protective finish - covers and seal the joint Improves frame alignment - adds rigidity to the joint Suits all 70mm frames - compatible with most windows UV-stable material - resistant to warping and cracking Maximise daylight - narrow profile gives larger glass area Popular colour choices - match frames outside and in Eco-friendly - recycled and low-energy manufacture Easy installation - simple one-part, hassle-free fitting Low maintenance - needs just an occasional wipe Manufacturer guarantee - a product you can trust The coupling can be easily cut to length, and quickly fitted to the adjoining frames, to add rigidity and a decorative closure to the joint. Suitable for vertical use when joining inline frames side-by-side, and horizontally when joining the head of one frame to the underside of another. Important: When coupling long frames, those in areas of high-wind load, or those requiring load-bearing capacity, a reinforced mullion should be considered instead.
