FDB’s Rocfast program saves time, money and mistakes by guiding customers through the process of specification, component matching, ordering, assembly, packaging and logistics – direct to site – worldwide. Now it covers the extra sealing requirements of high degrees of dust and water protection up to IP66 and IP67. Most common lock applications require the lower levels of IP54, however in external use IP65 may be needed and for harsh external or heavy hose down areas, then IP66 or IP67 is appropriate. IP67 entails submersion testing for even greater peace of mind.
