Understanding Nailer Parameters
Nailer parameters control how Mozaik builds the nailer boards inside your cabinets — their width, placement, and joinery method. Getting this right ensures your cut list and CNC output match your shop's construction style.
Nailer Parameters
NailW — Case Nailer Width
Sets the width of the top and bottom case nailers for base cabinets. This value applies to both nailers when a bottom nailer is used.
Important: Nailer placement inside or outside the case is determined by your Back Recess setting — not NailW directly.
- If Back Recess is less than nailer thickness → nailers are placed inside the case.
- If Back Recess is greater than nailer thickness → nailers are placed outside the case.
BotNail — Bottom Nailer
Controls which cabinet types receive a bottom nailer. Choose from three options:
- None — No bottom nailer on any cabinet.
- Wall Only — Bottom nailer added to wall cabinets only.
- All Cabs — Bottom nailer added to both base and wall cabinets.
FxShNailW — Fixed Shelf Nailer Width
Sets the width of nailers used with fixed shelves. Functions independently from NailW.
BNailBB — Bottom Nailer Below Bottom (Wall)
Controls whether wall cabinets receive a nailer below the cabinet bottom. This parameter is inactive in some construction methods and will appear grayed out when not applicable.
SplitFixShNailers — Split Nailers for Fixed Shelves
When set to Yes, nailers for fixed shelves between partitions are split rather than running as a single board. Useful for certain construction styles where a full-width nailer isn't practical.
NailerDado — Dado Depth: Nailer into Ends
Sets the depth of the dado cut where nailers join into the cabinet ends. A typical value is 1/2".
NailerQDado — Nailer Qualified Tenon Thickness
Sets the thickness of the qualified tenon on nailers when a tenon joinery method is used. Set to 0 to disable tenons.
NailerBlindSetback — Blind Dado Setback for Nailers
Sets how far back the blind dado is set from the front edge of the nailer. Set to 0 for no setback.
NailerTenons — How to Tenon Nailers
Defines the tenon style used on nailers. Options include Blind Front and Blind Front & Back depending on your construction method.
Quick Reference
| Parameter | Controls |
|---|---|
| NailW | Width of top and bottom case nailers (base) |
| BotNail | Which cabinets get a bottom nailer |
| FxShNailW | Nailer width for fixed shelves |
| BNailBB | Bottom nailer below wall cabinet bottom |
| SplitFixShNailers | Split fixed shelf nailers between partitions |
| NailerDado | Dado depth for nailer-to-end joint |
| NailerQDado | Qualified tenon thickness (0 = none) |
| NailerBlindSetback | Blind dado setback distance |
| NailerTenons | Tenon style for nailers |
Common Issues
- Nailers appear on the wrong side of the case: This is controlled by your Back Recess setting relative to nailer thickness — not a nailer parameter itself. Compare Back Recess to NailW/material thickness to diagnose.
- Bottom nailer missing on base cabinets: Check BotNail — if set to Wall Only, base cabinets will not receive one. Change to All Cabs if needed.
- Grayed out parameters: Parameters like BNailBB are inactive for certain construction methods. If a parameter is grayed out, it doesn't apply to your current method.
- Tenon or dado not generating: Confirm NailerDado is greater than 0 and that NailerTenons is set to the correct style for your construction method.
Troubleshooting
- If nailer changes aren't reflecting in the model, close and reopen the room file to force a refresh.
- NailerQDado and NailerBlindSetback default to 0. If you're seeing unexpected joinery, verify these aren't set to a non-zero value unintentionally.
