Choose the Correct Fit
Match this plate to core body 48-20-5140, not just a similarly sized bit. Confirm the thick wall design and 2-1/2 in diameter.
Use centering pin 48-20-5199 with the correct adapter shank for the hammer. Check the complete core assembly before starting.
Installation & Care
Isolate the hammer while fitting the guide and pin. Follow the core-bit instructions for forming the initial groove and removing the guide assembly.
Inspect the plastic plate for cracks, wear or distortion. Replace a damaged plate before it can compromise the next hole start.

Important Product Questions
Can a guide plate of the same diameter fit a different core system?
Do not assume it will. This plate is matched to thick wall core body 48-20-5140; verify the body and centering pin together.
Does the plate replace the centering pin?
No. It works with centering pin 48-20-5199. Check that both matched components are available for the starting operation.
Should the guide stay installed for the whole hole?
Follow the core-bit starting procedure. The guide and pin position the initial cut; remove them when instructed before continuing to the required depth.
