What it is
SizeDoctor V3.0 is a manual traction device made by Size Master. A vacuum cup sits at the top, two metal rods run down to a base holder, and extension rods let you set the frame length. A grip-handle hand pump creates gentle suction in the cup; a pull-release valve lets the air out.
What’s in the box
- 1 × vacuum cup with pull-release seal valve
- 2 × main rods with base holder
- Extension rods for adjusting frame length
- 6 × silicone sleeves – three sizes, two sets
- 1 × grip-handle hand pump
- English instruction manual
How it adjusts
Add or remove extension rods on both sides to set the frame length. Always use the same number of rods on each side so the frame stays level.
How to use
- Choose the sleeve size that fits comfortably without pinching.
- Fit the sleeve into the vacuum cup.
- Set the frame length with the extension rods.
- Position the device and attach the hand pump to the valve. Squeeze the grip gently until the cup holds – do not over-pump.
- To release, pull the seal valve to let the air out.
Please read the included instruction manual in full before first use and follow its guidance on fitting and wearing time.
