This is a magnetic holder with a hole through to accommodate a zip tie. If you can't find a standard holder for whatever you're planning, then this is the holder for you! The hole is a little over 1/4" which should fit most light to medium duty zip ties. The dimensions are 1 3/4" W x 1" L x 1" H. The curvature on the front is appropriate to accommodate from smaller to larger diameter objects. This holder is ideal for tubing, piping, heaters etc.
