Choose the Correct Fit
Match the spacer to the rig model before ordering. This version is specified for 4115 and 4120; check the motor and bit limits as part of the complete setup.
Unplug the equipment and secure the cradle before fitting. Engage the spacer’s square key with the motor slot and use the specified motor-side fasteners.
Installation & Care
Fasten the spacer and motor to the cradle using the specified cradle-side screws and lock washers. Check the exact listing for supplied mounting hardware.
Check that the cradle and motor remain rigid before coring. Secure the rig to the work as its manual requires; the spacer does not replace an anchor or vacuum attachment.

Important Product Questions
Does this spacer fit every DYMO-RIG stand?
No. This version is specified for 4115 and 4120 setups. Other stands use different spacer arrangements.
What connections should I check before fitting it?
The motor side uses 1/4-20 socket-head screws and the cradle side uses 3/8-16 socket-head screws, with lock washers. The square key must engage the motor slot.
Does the larger clearance change how I secure the rig?
The rig must still be secured and adjusted as its manual requires. Confirm motor and bit suitability and check for cradle movement before drilling.
