Takeaways

• The HDMI lock protects your HDMI cable from accidentally coming out during a shot.
• It somewhat protects your cables from breaking off, which is very easy in the case of HDMI ports.
• The built-in cable management system can take about 2-3 cables so you don’t have any dangling bits that could potentially get caught up in something.
• If you’re using a cage, make sure the cage can accommodate the HDMI lock, or at least have a lock of its own.
