Gainsborough Trilock Traditional Leverset Double Cyclinder Bright Chrome 890TLEBC
The Gainsborough Trilock Traditional, SKU: 890TLEBC, is a classic entrance set for external doors. The double cylinder allows the deadbolt to be locked and unlocked with a key from both the inside and outside, providing maximum security. It is reversible for left- or right-hand doors and is designed to fit a standard 54mm hole with a 60mm backset. All Trilocks feature tarnish-resistant finishes that can be matched in look and feel to your favourite interior levers.
Door Functions Explained
Gainsborough supplies the latch or lock with the handle set. The function you choose determines what comes in the box.
| Function | How it works | What comes with it | Use |
|---|---|---|---|
| Passage | Non-locking. The lever operates from both sides at all times. | The passage tubular latch is INCLUDED. | Hallways, wardrobes, and any internal door that does not lock. |
| Privacy | Locks from the inside with a button or turn, with an emergency release outside. | The privacy tubular latch is INCLUDED. | Bathrooms, ensuites and bedrooms. |
| Entrance | Key-lockable. Supplied with a cylindrical (key-in-lever) lock. | The cylindrical lock and keys are INCLUDED. | Front and back doors, where a cylindrical lock is acceptable. |
| Dummy / Fixed | A fixed lever with no latch and no moving parts. | SINGLE handle only (not a pair) — supplied with the spindle. No latch. | A fixed panel, or the inactive leaf of a double door. |
If you want a full mortice entrance rather than the cylindrical lock, the mortice lock is ordered separately. Gainsborough's mortice locks are double-cylinder, so the cylinder and keys are built in.
Separate Entrance Kit — Sold Separately
The handle set above comes with its latch or cylindrical lock. If you want a full mortice entrance instead, order one of the lock bodies below in addition to the handle.
| Code | Lock body | Backset | Notes |
|---|---|---|---|
| 755-60 | Double Cylinder Mortice Lock | 60mm backset | Keyed from both sides. Cylinder and keys are built in. |
| 775-60 | Roller Bolt Mortice Lock | 60mm backset | Roller bolt version, for doors that need a quieter, smoother close. |
| 760 | Sliding Door Mortice Lock | — | For sliding and cavity doors, not hinged doors. |
Gainsborough does not make a separate euro cylinder or escutcheon — the mortice locks above are double-cylinder, so the cylinder and keys come with the lock.
