Abstract
A fixed pile guide having a removable ring gate which restrains a pile within the pile guide. When in the closed position, the ring gate is secured to the guide by means of a pivotable arm. To release the pile and/or to convert the guide to an open pile guide, a cable secured to the arm is pulled which pivots the arm thereby releasing the gate from the fixed guide as well as releasing restraint on the pile.
