This CRL "Roll-Ezy" Ball Bearing Track Assembly is ideal for installations with bypassing doors. The assembly is easy-to-install, and once installation is complete the doors roll smoothly with frictionless ball-bearing operation. The assembly is designed for use with 3/16" (4mm) or 1/4" (6 mm) glass. Four Optional pre-cut sizes available for your convenience to eliminate waste and save on shipping.
Assemblies Include:
  • 1 piece of KV993 Upper Channel
  • 2 pieces of KV995 Shoe for Glass
  • 2 pieces of KV997 Ball Bearing Carrier
  • 1 piece of KV999 Lower Track
    System is designed for two sliding panels per openings. For more panels per opening, installer should fashion stops in lower track to restrict each set of two panels to one section of track.
    Each sliding panel height not to exceed two and one-half times the width.
    Max 50 pounds (22.7 kg) per linear foot
    For each foot of opening, use: 1' of upper channel and lower track and shoe (plus 1" per door for overlap), with 1-1/2' of carrier (1-1/2 times door width for each door). Glass is cut 1-1/4" lower than height of opening.
    Formula to calculate the Ball Bearing Carrier length is: Opening divided by 4, then multiply by 3 = Length of Carrier
