Flat-Flex® XT®

Over 2x the life of standard belts

When you require extra strength and support from your belt look no further than Flat-Flex® XT®. Flat-Flex XT’s unique smaller spaces increase the amount of belt joints across the width of the belt making the belt stronger. Flat-Flex XT’s unique design enables superior distribution of product weight across the width of the belt, reducing belt fatigue and increasing the life of the belt.

Joining Flat-Flex® XT® belts with clips:


If joining Flat-Flex® XT® belts with 1-space joining clips only, use a 1-space clip per every XT space across the width of your belt. We do however recommend the use of 1-space and 3-space joining clips when applicable (See chart below).

The use of 1-space and 3-space joining clips together will make a stronger belt joint and minimize the number of gaps in the belt versus using 1-space clips only.

Number of joining clips required - if using 1-space and 3-space clips together:

Important Notes:

  • 1-space clips are inserted into the XT (smaller) spaces only.
  • Each 3-space clip is composed of two XT spaces and one wide space.
  • A gap should appear in a wide space between each clip. A clip should be positioned in every XT space of the belt in order to engage with the drive sprockets.
  • Always avoid bending clips at the Z-bend. Bend at the center of the clip’s straight wire for optimal use.

Before you begin joining with clips:

  • Plan out the number, type, and placement of splice clips by laying them in position across the belt.
  • Ties can be used to hold belt ends together if needed.
  • Make certain that no two end loops on the splice clip hook around the same Z-bend.
  • All splice clip end loops should point in the same direction of the belt end loops, away from the direction of travel.

Begin installation at the center of the belt:

Using a 1-space clips only:
  • Insert one end loop up and through the belt to connect. Use needle nose pliers to grip and hook the opposite end loop around the Z-bend joint to complete the splice.
Using a 1-space and 3-space clips together:
  • Bend 1 XT space in the center, opposite direction of travel.
  • Insert the opposite XT space up and through the belt and use needle nose pliers to “lock” the space into place.
  • Use needle nose pliers to grip and hook the bent XT space and weave through to complete splice.
  • Straighten the wire with pliers or Wire Belt’s straightening tool.

Install remaining splice clips:

  • Continue splicing the remaining clips. There should be the same number and type of splice clips on each side of the center space.

Drive Component Setup:

With Flat-Flex® XT® conveyor belt, setting up your drive and idler shaft is fast and simple.
Flat-Flex® XT® drive shaft setup
To setup the drive shaft, install one drive sprocket per XT space along the full width of the drive shaft (figure above).

Flat-Flex® XT® idler shaft setup
In setting up the idler shaft, install one drive sprocket per outside XT space of your belt (figure above). Then, install one blank on each of the inside XT spaces across the width of the belt. Make sure to fully secure each component along the shafts.

Sprocket Placement

With Flat-Flex® XT® conveyor belts, sprocket setup is simple. One sprocket is used in each of the XT (small) spaces only across the entire width of the belt. Sprockets should have an even amount of clearance on both sides between each Z-bend.

The correct clearance must be present between every sprocket and its adjacent Z-bend. This cannot be emphasized too often. Belt life will be severely reduced if the Z-bends come in contact with any component of the conveyor.

General Best Practice: Wire Belt recommends that only genuine Wire Belt sprockets and blanks be used. Commercially available sprockets can cause the belt to surge, jump teeth, and may cause premature failure.
