10 Feet Tinned Copper Braid Internal Reinforcement Stained Glass Panels Flex-Bar
This product is constructed of braided tinned copper wire, measures 1/8" by 1/32" and is used to provide internal reinforcement in any stained glass panel. Whether you use copper foil or lead came, this can be easily soldered into any piece to prevent bowing. Use to strengthen lamp shade apertures and bottom borders. May be used to give added vertical support where needed as in pool table lamps.
Most people use this product to eliminate external bars. How much can be eliminated is a tough question because it depends on the size, design and intended installation of your panel. Remember to error on the side of stronger.
