These tensioners are very useful except that the choices I have made are that they are a little too short for the house from above, to be able to catch both ends of the house ironing. Of the three tensioners, only allows to hook the two edges of the house from above, but I have two house one over the other, the lower one is wider and allows me to hang both edges so that my two houses are well kept and all is secure. This prevents the edge of the houses date back when we go back sheets.
