ABSTRACT:
A kit of reusable paint masks for door hinges for use when painting a door and frame comprising two masks, one mask for protecting the door hinge butt plates and the other mask for protecting the pin cylinders. The door hinge butt plate mask is made of a flaccid material having spaced flexible magnetic elements for attachment to magnetically attractable door hinge butt plates by magnetic force. The magnetic elements enable the mask to be readily adjusted for proper registration without requiring removal and reapplication of the mask. A tab is also provided for removal of the mask after completion of the painting. The pin cylinder mask is made of a resilient material of U-shaped transverse cross section with the sides and back engaging the pin cylinder to cover it. Both masks can be manufactured in a variety of standard and specialty sizes.
