This bracket will allow the use of face shields with hole punched using a US standard 3 hole punch. Three 0.281" diameter holes spaced at 4.25 inches.
A 30 inch length of 3/8" elastic secures it the wearers head. The elastic loop may be created by stapling the ends together (don't use cheap staples) after looping it through the bracket.
Legal size (8.5 x 14 inch) transparencies or equivalent size clear plastic are recommended.
A Swingline Smarttouch 20 punch will allow the wider sheets to be used. Some will only allow letter size sheets.
