Select Southco M1 flush-pull, push-to-close RV access-door latches by the manufacturer's actual panel-thickness ranges, latch size, locking function and material. The nearly identical M1-61, M1-62 and M1-63 faces do not mean the mounting brackets fit the same door panel.
Official manufacturer drawings and specifications
Southco publishes an individual technical drawing, catalog page, performance data and downloadable CAD for its M1 flush-pull latches. Use the manufacturer's actual drawings for screw spacing, keeper engagement and panel thickness; compare the installed latch with the manufacturer's technical drawing.
Browse original Southco M1 drawings and latch variants. Example: Southco M1-61 technical specification.
Choose by panel thickness, then finish
M1-61 black plastic or M1-61-8 stainless; 25.5 mm (1.00 in) nominal grip.
M1-62 plastic or M1-62-8 stainless. Keeper and mounting dimensions must be checked.
M1-63 plastic or M1-63-8 stainless. Verify measured door skin plus mounting support.
M1-64-8 stainless; not the same bracket configuration as thin-panel M1-61.
Small-size exception: M1-15-61-8 is a small stainless latch for 1–21 mm panel thickness and a 23 mm nominal grip; this is a different physical size series and should not be treated as a standard medium M1 replacement.

Panel thickness controls which mounting arrangement can clamp the door. Grip is a separate latch/keeper engagement dimension and is approximately 25.5 mm for these medium variants.
M1-41, M1-42 and M1-43 are related key-locking families; they require their own factory mechanical dimensions and keying checks. They are not direct replacements for the non-locking part numbers above.
The smaller M1-15-61-8 has different proportions from M1-61-8. Use the manufacturer's drawing to measure the outer bezel, cutout, fasteners and depth.
Before ordering or installing
Measure the door panel thickness, latch cutout, keeper setback and clearance behind the inner skin. Identify whether the original mechanism uses a mounting bracket, screws and an additional keeper. Confirm material and finish, particularly if an exterior compartment is exposed to water or corrosion.
For conventional baggage-door cam locks and slam latches, use the separate baggage-door latch and cam-lock reference; those are different mechanisms.
Safety: Test the complete latch and keeper with the door open. Do not use a non-locking access latch in place of a required secure lock or emergency-release mechanism.
