Customer Comments:

  • I have repaired bi-fold doors for years and have stacks of old doors that were unusable. There was no way to repair them so they would work without having to go back for maintenance calls time after time. These new Maintenance Engineering Specialties products have solved this problem with both my new and used bi-fold doors. I wish we would of had these products years ago...all the money, time and bi-fold doors we have thrown out the window... what a shame.

  • Way to go MES!

  • My new way of repairing new and used bi-fold doors is, do it once and do it right! STOP throwing away time and money. Use these products on your new doors for maintenance free operation for LIFE...and fix your old doors in minutes.

  • Thanks MES!
