The 12.30pm meeting is at Frosts Group offices at Airport House, Purley Way, Croydon CR0 0XZ.
The company is expected to be liquidated on that date. Maingate is insolvent and Frosts have been working with the directors for six weeks to try and get as much value out of the business as possible, said Frosts' Jeremy Frost.
Anton Degreef is director. Ole and Peter Valentin were directors up to the end of 2014. Maingate was best known as importer of County Wheelbarrows.
