Gainsborough Trilock Cove Harper Entrance Set

Gainsborough Trilock Cove Harper Double Cylinder Entrance Set

The Trilock Cove Harper entrance set brings the refined, contemporary Harper lever to your front door, matched with Gainsborough's patented 3-in-1 Trilock technology. The Cove series features a fresh backplate with sleek curved corners and a matching tapered lever — creating a modern, cohesive entrance that pairs naturally with contemporary joinery and new-build interior palettes.

Available in Satin Chrome and Matt Black, with a 186mm lever length and 60mm backset, the Cove Harper suits both left- and right-hand doors.

How Trilock Works

When unlocked and unsnibbed, Trilock operates as a passage set. Press the inside button for lockset mode. The double cylinder deadbolt with 20mm throw is operated by key from either side for maximum security.
