For closets in the PAC Mozaik Closet Library, PAC recommends full line bore unless you absolutely have to switch. Line bore gives the easiest install and full adjustability. Custom bore drills holes only where needed for a cleaner, hole-free look, but you give up adjustability. Shotgun bore means a part creates its own hole only where it sits.
What is the difference?
- Full line bore (recommended): panels carry a full pattern of holes. Easiest install, best adjustability for the customer, and all hardware and accessories drop right in.
- Custom bore: holes only where needed. Adjustable shelves still get full holes, but fixed shelves, hanging rods, drawer hardware, and doors are shotgun bored. Cleaner, with no visible holes, but you lose adjustability and add manufacturing care.
What is shotgun bore?
A part (like a fixed shelf) creates its own hole in the panel, only where it sits. With line bore the holes are pre-drilled in a full pattern and parts just assume a hole is there.
PAC's recommendation
Stick with full line bore unless you truly must switch (no drill block, a picky customer, or a high-end home that wants no holes). The library handles custom bore too. See switching to custom boring.

Both boring strategies are pre-built into the PAC Mozaik Closet Library. Start on full line bore for easy install, switch to custom bore when a job needs it, with no setup required.
