The DISEC Sferik Basic BD68D1P is a mechanical protector for Euro profile cylinder locks, featuring a hemispherical body and 31 mm fixing centres. It is designed for doors with compatible mounting arrangements, including ATRA lock configurations using this fixing-hole spacing.
The hemispherical external body shields the accessible section of the cylinder and reduces gripping surfaces for tools used in tampering attempts. The front opening permits normal key insertion, while the oval escutcheon covers the mounting area on the door.
The BD68D1P differs from the BD16 in its 31 mm fixing arrangement, an essential specification when selecting a replacement protector.
| Type | Hemispherical mechanical cylinder protector |
|---|---|
| Application | Euro profile cylinder locks |
| Body diameter | Ø50 mm |
| Body projection | 25 mm |
| Escutcheon height | 85 mm |
| Escutcheon width | 65 mm |
| Escutcheon thickness | 6 mm |
| Fixing centres | 31 mm |
| Fixing thread | M6 |
| Configuration | D1 |
The BD68D1P is intended for locks with 31 mm fixing centres. Checking this measurement is particularly important when replacing an existing protector: versions with 38 mm fixing centres are not directly interchangeable unless the door and lock mounting arrangement is compatible.
Before installation, also check the cylinder position, its projection from the external door panel, the escutcheon dimensions and correct key access.
Before ordering: compare the 31 mm fixing centres, overall dimensions and fixing arrangement with the existing lock. Contact Matteoda customer service for help selecting the correct version and for estimated delivery times.
