We recently received pictures of the Truth 11.10 Awning Operator. The homeowner said the numbers she found on the operator were 45002 and 40008. The Truth Window Hardware numbers that start with a 4 are usually die casting numbers, and since the die cast housings are used on about 20 different versions of Truths operators. In this particular case the operator was the Truth 11.10 Awning Operator. But it could of also been the 11.12, 11.14 or the 11.16. The best way for us to determine which operator you have is have the numbers off the arms.
