The cord grip included with our camera enclosures is normally shipped without a hole for your camera cable or cables. The grips cannot be predrilled because the hole size must match the outside diameter of your cord. We suggest using an end mill, but careful use of a drill press can work in a pinch.
But why not make your job easier and expedite installation? We suggest letting us predrill the cable entry hole for you. Just specify the diameter of the cable you’re using, or purchase it with one of our cables. Installation will go easier, and you’re assured of a tight of seal.
Please specify the OD of the cord you're using, or which one of our cords you're using.
