RAM Mounts Pin-Lock Security Knob for C-Size Socket Arms (RAP-S-KNOB5U)
13,36 € +VAT

RAM Mounts Pin-Lock Security Knob (RAP-S-KNOB5U) replaces the standard knob on RAM C-size (1.5") arms and mounts with a low-profile security knob that is tightened and loosened with the included Pin-Lock key knob. It deters theft and tampering of mounted devices at a lower cost than most keyed locking knobs, while still giving enough leverage to tighten the mount securely in heavy chop or high-vibration environments. Pin patterns are randomised; fixed-pattern versions are available separately for fleets that want one key for every mount.

📦 What's in the box – RAP-S-KNOB5U

  • Pin-Lock security knob – 5/16"-18 female thread, for C-size arms
  • Pin-Lock security key – key knob for tightening and loosening

💡 You might also consider a RAM C-size double socket arm for a new installation, or the key lock knob with brass insert if you prefer a classic key lock.
