Hoop Gauges

Hoop gauges measure the spacing between the uprights of the hoop. They are introduced into the jaws of the hoop at half-ball height once it is set in the ground to measure the gape.

Hoop gauges are useful for the general setting of hoops for club play. For tournament play however the hoop gape is set to be a fixed width larger than the the diameter of the largest ball in the set.


Feeler GaugesFeeler Gauges

For top-level play the hoops may be set to as little as 1/32" (total) wider than the ball. Consequently a set of shims of known thicknesses (feeler gauges) are useful for checking the clearance between the ball and the hoop. Note that the gauges should be lightly inserted not forced into the gap.


Hoop Lifter

Mike McClure of Amber Tech (NZ) has devised a folding lever mechanism for drawing reluctant hoops from the ground. Details of this hoop lifter can be found here Hoop Lifter courtesy of Mike McClure Hoop lifter folded, courtesy of Mike McClure

Ball Marking Plate

Again from Amber Tech (NZ) this is a plastic plate which is brought up to the ball to be marked and then the corners of the plate are marked. More details here. Umpire's Marking Board, courtesy of Mike McClure
