JDS have incorporated the RegalFrame design into its knockdown doorframe range. This is great news for those home designs that use brick on the lower floor and stud on the upper floor. The knockdown frame is very popular for country areas due to the fact it comes in 3 pieces and packed as one reducing the cost of country transportation. The mitre system that JDS has designed allows for each corner of the mitre to be opened and closed fitting the wall, resulting in an accurate and neat mitre joint.




Technical Specifications
The RegalFrame Knockdown doorframe is made from a 1.0mm Galvanneal. The frames come in 3 pieces consisting of a head, a hinge stile and a striker stile. These are then packed together to make a complete frame. The knockdown frame is available in all standard sizes and can also be made to suit special sizes. Most standard sizes are available ex-stock.
