Prisma Brass Turn Knob

Features

The PRISMA Series round thumbturn with emergency release is crafted in brass, 50mm in diameter and 11mm thick, made for back-to-back fixing with an 8mm spindle. Its low, round shape sits neatly on the door face, with a release function for emergency access from the outside.

Designed for privacy doors where an external release is needed but a lock-status indicator isn’t, this thumbturn pairs naturally with other pieces in the PRISMA collection, giving specifiers a consistent look across a project’s privacy and lock sets.
