APPLICATIONS — DOOR HANDLE & KNOB ATTACHMENT Use cases: older British interior door handles, Victorian door knobs, period escutcheons, antique-style mortice handles, retro lever handles, restoration projects with original-spec hardware. Sectors: residential interior doors (especially older properties), restoration, period property refurbishment. Compatible with: M3-thread door handles (common on older British handles; modern handles typically use M4 — verify before ordering). Note: not for fire doors (which require certified intumescent fixings). INSTALLATION GUIDANCE 1. Position the handle/escutcheon on the front face of the door. 2. Insert the female sleeve through the spindle hole from the back of the door. 3. From the front, insert the male slotted bolt into the sleeve through the front handle/escutcheon. 4. Use a flat-blade screwdriver to tighten — do NOT over-torque (slotted heads strip easier than Phillips). 5. Spindle and latch supplied separately.
