We still get calls for the older style fusible link armed door closers.  With most manufactures not selling them anymore, we had been hunting for an alternative.  We now offer an inexpensive fusible link armed door closer and have them in stock.  This door closer, the International Door Closer 8151-F features a non sized adjustable spring, closing and latching speed adjustments and ships with a parallel arm bracket.  The hole spacing is 3/4″ x 9-1/16″ and can be mounted regular arm, parallel arm or top jamb mount.   It also has a five year warranty.  With a price of $105.00 each, it is a third of the price of the big boys.  This is a lower cost solution to having to wire your building for the latest fire alarmed wired door closer.
