A casement window is hinged at the side and swings open like a small door, unlike a sliding sash window that moves vertically. Casements appear in both timber frames and steel or metal frames, and each needs its own casement window handles, fasteners and stays to open, close and hold the window in place. This guide covers timber and metal casements rather than uPVC.

Most timber casements are either flush, sitting level within the frame for a traditional look, or stormproof, with a stepped, overlapping edge for better weather resistance. Both use the same core casement window handles, but the exact fastener and hinge can differ, so check your window before choosing your casement window handles.

Timber casements take the widest choice of casement window handles and stays. Steel casements are slimmer and often need dedicated fittings - From The Anvil produce a steel window hardware range built specifically for steel-framed windows, giving smooth operation and a coordinated look throughout a property.

Every casement relies on three groups of hardware working together to stay secure, weathertight and easy to use. Get your casement window handles and fittings right and the window seals properly and lasts for years.

• Handles and fasteners - the casement window handles that pull the window shut and hold it against the frame.
• Stays - the arm that holds the window open and stops it slamming in the wind.
• Hinges - the pivot that lets the casement swing open and closed.

On a side-hung casement, the item most people call the handle is technically a fastener. The casement window fastener fits to the opening edge and rotates to draw the window tightly shut against draughts and rain, so it controls both security and weather performance. See the full range of casement window fasteners at Trade Door Handles. Below are the main styles of casement window handles you will come across.

The fastener mounts on the stile (the vertical edge) of the opening casement, on the side furthest from the hinges, and engages a plate on the frame. Handing matters - casement window handles are supplied for windows opening to the left or right, so confirm which way yours opens before ordering.

The fastener needs a keep on the frame to grip. A hook plate sits on the surface and the fastener hooks over it, which suits stormproof windows. A mortice plate is recessed into the frame for a neater finish on flush casements. Fitting the right plate is what lets your casement window handles close firmly and stay shut.

A night vent fastener has an extra notch that locks the window slightly open for secure ventilation, then closes fully when you want. Night vent casement window handles are among the most popular for bedrooms and kitchens.

A cockspur casement window handles are a traditional wedge-shaped fastener that closes down onto a small striker or wedge plate fixed to the frame. It is one of the most common casement window handles on older steel windows and period timber casements, where the sloped spur pulls the window tightly shut against the seal. Cockspur casement window handles are usually handed left or right and come in different stem heights to suit the depth of the frame rebate, so check yours before ordering. They pair well with black, pewter, chrome and antique finishes.

A casement stay is the flat, drilled arm that holds the window open at a chosen angle, working alongside your casement window handles to give full control of the opening. Our casement window stays collection covers peg stays, friction stays and locking options.

Traditional peg stays come in three lengths, though many modern versions are only made in the 10 inch size:

1. 8 inch - smaller windows and top vents.
2. 10 inch - the most popular all-round size, and often the only length made today.
3. 12 inch - larger casements that open wider.

Measure your casement before pairing stays with your casement window handles.

A casement stay locking pin slides through the holes in the stay arm to hold the window at a fixed opening and add a little security. Pins are often sold separately, so check whether your stay includes one. Many buyers order spare pins to match their casement window handles and stays.

A peg stay locates over pegs at set positions, while a friction stay holds the casement at any angle by tension and can double as the hinge on steel windows. Peg stays pair with separate casement hinges.

The hinge lets the casement pivot open. Timber windows usually take a butt hinge or a purpose-made casement hinge, while steel windows often rely on friction stays. If you are replacing them, our casement hinges and window hinges range covers the options - match the hinge finish to your casement window handles for the tidiest result.

Yes - casements can be made very secure. Lockable casement window handles and key-locking fasteners stop the window being opened from outside, which matters most on ground-floor and accessible windows.

• Locking fasteners - key-locking casement window handles for everyday security.
• Window restrictors - limit how far the window opens, supporting the common 100mm child-safety guidance.
• Night vent fasteners - secure ventilation without opening the window fully.

Near the sea, salt air corrodes ordinary finishes fast. Grade 316 stainless steel casement window handles, fasteners and stays resist corrosion far better, making them the sensible choice for coastal and exposed properties where standard hardware would soon fail.

Casement window handles come in a wide palette, including polished and satin chrome, polished and satin brass, pewter, antique black and matt black. For a coordinated scheme, match your casement window handles to your door handles and other ironmongery across the property.

Understanding how the parts differ helps you match casement window handles and fittings first time:

• Fastener vs stay - the fastener holds the window shut and secure; the stay holds it open. Most casements need both.
• Hook plate vs mortice plate - surface-mounted versus recessed keeps; stormproof windows usually take a hook plate, flush windows a mortice plate.
• Peg stay vs friction stay - fixed opening positions versus infinitely adjustable tension.
• Cockspur vs standard fastener - a traditional wedge for period steel and timber windows versus modern casement window handles.
