Drilling
It is also recommended to drill an additional 1/2” (12.7 mm) of depth beyond the length of the fastener being used to
ensure that debris does not block the entry of the anchor.
• This can be done by marking your drill bit with a piece of tape.
• While it is recommended that a vacuum be used to clean up debris, this will not account for all the debris that will
settle at the bottom of the drilled hole.
