Each OTM rail kit comes complete with swivel arms and fixings for attaching HYDRA 64, HYDRA 32 and HYDRA 26 LED Lights. These can be fixed into any position throughout the length of the rail by simply sliding it along and then tightening the fixing screw. With a single pivot point in the middle each arm they can be rotated throughout 360 degrees allowing the light to be mounted facing left to right, front to back or anywhere in-between.
