About our mounts

All our mounts are cut from Larson-Juhl Conservation / White Core mount boards as a minimum standard. All Conservation boards fully comply to FATG Conservation level. Whitecore boards meet FATG Standard level. We offer mountboards in 1400 micron (standard) and 2400 micron (extra thick)

We use state of the art computerised mount cutters which enable us to cut an abundance of aperture shapes accurately
