The arms stretch 21-1/2" across in the closed position. The housing is front side mounted with 4 screws. The spacing on the outside screws are 7" on center, and 6" on the inter screws. We find the number 30895 or 30895A stamped on the arm.
The Wi11454 handle in matching color is included with the operator along with the Sash Hook Wi20008.
Truth Single Arm Window Operator. This new style replaces the older tradiational size shown in the diagrams.
To determine hand of operator, if your sash lock (window lock), is on the left, you would use a left hand operator. And if your sash lock is on the right, you would order the right hand operator.
We sometimes find the number 45251 cast on the housing, and 40049 and 40050 stamped on the arms. This operator has a Nylon Wheel or Roller.

The Truth 14.80 hinge is the most common of the Truth Stainless Steel Casement Hinges. The stainless steel track is 10" long, the glide is a plastic coated steel. The most common problem on this hinge is the shoe. When the hinge is installed incorrectly or not maintained the shoe could pull out the window track. This Truth hinge is used on the Wi1510, Wi1511, Wi1516, Wi1518, Wi1531, Wi1532, Wi1594 and Wi2301.
This hinge is sold in pairs (one top and one bottom). If your window is the opposite hand, the top hinge goes to the bottom and the bottom hinge goes to the top.
The Truth 50.10 Maxim Dual Arm is one of the more popular new style operators. This operator is the same as the 50.00, but without the painted steel cover riveted to it. Some numbers we find on this operator are 41011 and 31876.
Truth 16.52 Sash Lock. A very common sash lock that tends to fail because the plastic slide breaks due to incorrect installation at the window manufacturer or being forced when there is a obstruction in the window opening. The new replacement model has a thicker plastic slide. Because the slide is thicker, the keeper, part # Wi41268 and Wi41269 might have to be shimmed with small washers.
Common numbers found on this sash lock are 21328 and 45189
Non handed (can be used on right or left hand windows).
Truth Encore Dual Arm Operator for Low Profile windows. Same as the Wi5010, but has a rectangular slide on the long arm instead of the standard models square slide.
