Add some history and drama too your doorway. Approx dimensions are 20cm high, 12cm wide and 4.5cm (deep) projection off the surface. The bolt length would suit a door approx 5cm thick or deeper if the fixing was counter sunk when fitting. Or simply cut down or switch the threaded bar for a longer one available in most diy stores or online , the thread measurements are imperial 1/4 20 if you need to change the length. Please see my other listings for more quality antique fixtures and fittings thanks.This item is made of brass.
