These are Gainsborough sliding cavity door sets featuring circular escutcheons. The first type is a passage set designed for general sliding cavity doors, offering a latching but non-locking function. It is ideal for areas where privacy is not required. The second type, on the other hand, is a privacy set best suited for bathroom and ensuite sliding doors, equipped with an internal turn button lock and an external emergency release. Both sets are compatible with doors 32-45mm thick and require a 54mm bore hole. They feature a 60mm backset and are part of Gainsborough's extensive range of sliding cavity door hardware, known for their stylish design and ease of installation.
