This is a locking cone that can attach any Moerman equipment to it for use at heights.
The locking cone is usually seen on top of the Moerman telescopic pole, but that is not the only place it can be used. You can pair it with other locking cone adapters to attach it to various poles. Combine it with the Gardiner locking cone adapter and you will be able to use Moerman equipment with the AR PRO carbon water fed pole.
The locking cone uses a clip that slips into the hole of the Moerman equipment handles and locks them securely in place.
