Reinforce & Secure Cabinet Carcasses

What happens here

Inspect all installed cabinet carcasses (both base and upper). For upper cabinets, which are not yet fully secure, add pocket holes along key joining edges and secure them to each other and to the wall studs using screws. Install 2x2 wood blocking behind the top front edge of the cabinets where face frames will attach, particularly in corners, to provide solid anchor points and tie adjacent cabinets together. Ensure all screws are properly countersunk and tight.

Goal: Secure all existing cabinet carcasses to the wall studs and each other, adding structural blocking and pocket holes where necessary for increased stability.
