Length in the hook
Measure from the point in one hook to the same point in the other hook. Mark the photo where the measuring tape starts and ends.
How to measure a screen deck
Always measure SPI, SPA and FL in the same way. Please note where you took the measurement; then we can include the correct production dimension on the quotation.

Work safely
Switch off the machine, secure it according to your own safety procedure and never measure on a rotating or freely hanging installation.
The three most important measurements
Use one measuring tape, measure straight and write the unit of measurement.
Measurement outside the hooks
Measure from the outside of one hook to the outside of the other hook. Always indicate that this is SPA.
Width of the flat part
Measure the flat part of the deck, without including the upright or folded hooks.
Measure in this order
If in doubt, measure in two places. Just report any difference or wear.
Lay the deck flat
Preferably use a clean, undamaged deck. A worn deck may be stretched or warped.
Measure SPI or SPA
Choose the size requested on the quotation and note which measuring method you use.
Measure FL and mesh
Measure the width of the flat part, the free opening and the thread thickness.
Photograph both hooks
Take a photo straight from the side and put a measuring tape or ruler in the frame.

A used deck may differ
Stress, wear and deformation change the size. Measure several points if the deck is crooked and tell us that you measured a used deck.
