How Oval Profile Sash Locks Work
Understanding Oval Profile Sash Locks for Timber Doors
Oval profile sash locks deliver everyday handle operation with a separate, secure deadbolt. They’re ideal for timber doors in offices, schools, healthcare and heritage sites where oval cylinders are already in use. Common case depths are 2.5" (64 mm) and 3" (76 mm); the deeper case helps achieve a larger backset on thicker or fire-rated casings. For a cohesive setup, pair with Lock Door Handles on Backplates and choose a compatible Oval Profile Cylinder. If you need deadbolt-only solutions, see Oval Profile Deadlocks. For broader navigation, visit Locks & Latches or Mortice Locks & Latches, and explore complementary ranges in Architectural Ironmongery, Accessories and Door Furniture.
Need Guidance on Sizes and Cylinders?
Backset, Case Depth & Master Key Compatibility
When replacing an existing lock, confirm the backset, case depth, forend style, and the spindle/follower size for your handles. Select an oval profile cylinder length and function (key/key or key/thumbturn) to suit door thickness and master key requirements — note that oval cylinders use pin tumblers, not levers. For matching looks and finishes, browse Door Furniture and premium ranges from From The Anvil, Carlisle Brass, Heritage Brass and Frelan Hardware. If you need help, please contact us.
