INFORMATION |
PG cable glands are in the process of being phased out. These will be replaced with metric type glands. Rose+Bopla’s PG cable grips employ a special thread not generally available in America, therefore we are standardizing with metric.
Accordingly, Rose+Bopla has a limited stock of taps for sale to customers wishing to drill, tap and install Rose+Bopla’s PG type
cable grips at their own facilities. We do not offer metric taps, however they can be purchased through your local hardware
supplier.
Listed below is the necessary information for drilling and tapping holes for Rose+Bopla’s PG or metric cable grips and the appropriate tap part number. Thick wall applications require that you tap holes for cable glands. Thin wall applications may be drilled through with a nut.

If you are going to use a polyamide grip with a nut and are not going to tap the hole, you will need to drill a larger hole to push the grip through. Use the chart below for the correct size hole.
