Setup, Compatibility & Care

Installation should be performed by measuring the door thickness to ensure the latch fits the existing mortice pocket. Always verify that your door furniture is compatible with the bolt-through holes on this specific model. For maintenance, a light application of a high-quality lubricant on the latch tongue once or twice a year will ensure smooth operation for the life of the product. Keep the mechanism free from excessive sawdust or debris during installation to prevent internal clogging.
