A storage bracket designed to secure and store a firearm is generally comprised of a frame and a spring-loaded stop that is adjustably secured to the frame. The device substrate includes a flexible substrate, a display unit and a first terminal part. The contact element has a piercing element extending into the receiving channel that electrically contacts the electrical conductor. The lower molecular weight polymer is highly viscoelastic in character and is preferably an HVI-PAO; this component in the lubricant which provides unexpectedly high film thickness and unexpectedly good wear protection under conditions where the second, higher molecular weight polymer may lose some or all of its thickening power.
