Specify Opening

Specify the opening or mesh count, wire diameter and alloy required.

Supply Dimensions

Give the overall (finished) dimensions of material, and the quantity required.

Specifications

• Size and make of machine (if known)
  
  
• Exact finish dimensions of section. Measure from either outside to outside of hooks, or inside to inside of hooks, (figure 1) "OCW" can be determined by measuring the dimensions of the clear clamping width between the vibrator side plates and subtracting 1 to 1 1/2 inches.
  
  

  ("ICW" is measured from inside of hooks.)

  Figure 1 Measure Clear width between the side plates and subtract 1 to 1 1/2". This will give you the "OCW" for screen required.

  
  
  
  
• If a slotted opening is required, the direction of the slot should be specified in relation to the hook strips. Number of shoot wires should also be specified (most common is single shoot and triple shoot). Slots "RA" or "Against the flow" indicate the slots are right angle to the hook strips. (Figure 2) Slots "SP" or "With the flow" indicate the slots are parallel to the hook strips. (Figure 3) (Note: End Tension screens will change the slot direction terminology.)

• If two or more screens are used for length, advise is a lap is desired. Give the overall length first then specify the length of the hook and amount of screen overlap needed (figure 4)

• Specify the type of metal to make the hook strips, and advise any special conditions such as: End tension, Welded hooks, holes punched, one hook up; one hook down, center crown, rolling, brazing.
