Retractable Lock Box with Key Tether

The Master Lock retractable key tether is designed to be used with the Master Lock mechanical and Bluetooth enabled lock box families. It ensures that the key remains secured to the lock box, preventing guests from taking the key with them after accessing the property. This key tether is compatible with the following Master Lock lock boxes: 5400, 5401, 5414, 5415, 5420, 5424, 5425, 5440, and 5441. The retractable cable can extend up to 36 inches (91cm) and is attached to the inside of the lock box using very high bond (VHB) tape. Keys can be attached to the end of the retractable cable using a loop end with adjustable collar or with a key ring.
