The metal tophat fitting is the most common method for attaching a large speaker, such as a PA speaker, to the top of a stand by simply fitting the tophat to the base of a speaker. There are no moving parts to jam, no flimsy brackets to snap or strip their threads, just a solid metal, recess into the body of your speaker cabinet, that the main pole (or 'mast') of the speaker stand slots into. Gravity takes care of keeping your speaker secure on the stand, while still offering 360 degree movement.
Internal Diameter - The internal diameter of this Top Hat is 36mm, this is a standard size, perfect for use with 99% of speaker stands on the market.
