Die Cast Zinc Alloy – Flanged
1/4-20 inside thread
Easy to install:
Using a 3/8″ (.375″) drill, drill to a depth of at least .65”.
Place the insert into the opening of the hole and screw insert into hole using a M6 or 7/32 Allen wrench. Screw so that insert is flush with bottom of speaker.
Remember, most speakers already have inserts installed. These are usually only required for custom DIY projects.
