A mortise handle set must match the door thickness, lock body, spindle, cylinder and fixing geometry as one interface. For OEM purchasing, approve the complete set on a representative door before freezing finish, packaging and repeat-order details.

The source library lists mortise handle sets for 40-80 mm doors and identifies Custom Handle Sets as a family covering entry-door mortise sets, interior levers, window handles and aluminum door handles with locks. Exact lock-body compatibility remains configuration-specific and requires a drawing or sample.
Measure the finished door, including skins, glass, panels and any cladding. A nominal door size can change after finishing, and a handle fixing that works on a bare core may bottom out or leave insufficient thread engagement on the production leaf.
Compared with generic replacement handles, an OEM set must control the lock body, spindle length, cylinder opening, rose or plate coverage and fixing method. The visible lever is only one part of the installed interface.
Two handles can look similar while using different spindle lengths, roses, fixing centers or lock followers. A thicker door may need a different through-bolt or spindle arrangement. Do not approve from a catalog photograph alone.
The supplied product reference identifies aluminum, zinc alloy and related handle-family configurations, with thickness ranges depending on the set. It does not disclose a universal product certificate number, price or MOQ. Request the exact material, coating or finish, corrosion requirement, packaging and inspection scope in the quotation.

The source reference lists mortise handle sets for 40-80 mm doors. Confirm the finished construction and exact configuration before ordering.
No. Confirm lock body, backset, spindle, cylinder, follower, handing and fixing geometry on the drawing and sample.
No. Final approval should use the production-intent door, lock body, spindle, cylinder and finish because thickness and cladding affect fit.
