Spider 4M
Male hex · More pump clearance · Striker notch
Four updates, one familiar platform.
The comparison is mainly about engagement and access—not a completely different way of winding line.
01 / Drive connection
The spindle moves from recessed to projecting.
Spider 4
Spider 4 uses a female hex connection recessed into the winding housing.
Spider 4M
Spider 4M uses a projecting male hex connection engaged with the matching socket.
Plan for the matching hardware. The connection changes how the driver meets the tool.
02 / Pump clearance
More room around the vacuum plunger.
Spider 4
The original frame leaves the standard clearance around the manual pump.
Spider 4M
The revised frame opens the area around the plunger for easier finger access during setup.
The vacuum routine remains manual. Establish and monitor the hold exactly as instructed.
03 / Anchoring & spindle
4M adds a striker notch and reinforced winding hardware.
Spider 4
Spider 4 uses the original integrated frame and standard spindle construction.
Spider 4M
Spider 4M adds the door-striker notch plus revised internal spindle gears and bearings.
Use the notch only as directed. Fully seat and align the frame before applying winding tension.
