This Oben Twist-Lock Assembly for Tripod Leg (13mm Diameter) is a replacement part for the Oben CT-3500 tripod.
Note! Each tripod has twist-lock assemblies of different sizes – this assembly replaces only one size for the compatible model listed. To determine if this is the correct size assembly, measure (in millimeters) the diameter of the threaded part of the leg section at the bottom of which you'd like to exchange the twist-lock assembly. Add 1mm, and select the assembly size that corresponds to your number.
