The PaxLock Pro cover plates enable you to install PaxLock Pro onto a door that has previously had a handle or other door furniture fitted to it, where drill holes or markings are wider than the PaxLock Pro unit. The cover plates discreetly hide any remaining holes or markings, allowing you to save time and money on refurbishment.
