Hi. My customer has a quite old bay window in good shape. The casement flanker hardware is tired. The right side does not operate. The left side does, but due to play in the armature, the assembly pops off the sash where the aluminum track has the gap for removal/maintenance. I am looking to replace the armatures, crank assemblies, handles, and the track at the bottom of each sash. One LH Oper, One RH Oper. Crank Base is a "Golddust" color and measures about 4-1/4" x 2-1/8". Locks seem fine. Thanks. -Kris

Thanks for reaching out to us, Kris. It's tough to make out your operator without seeing the whole thing, but I am strongly reminded of our 39-013. I think yours is just an older version. We also sell the 39-014 for the opposite side, as well as the 39-205 handle and 39-505 track. Look these parts over and see what you think.

Hi Tom,

Thanks. I was on vacation last week. I think we are headed in the right direction I am curious on a couple of notes. The track definitely seems like it can work. The handle is definitely entirely different. Is there a matching hardware cover for that new handle to seat on? Original is a "gold dust" type color and none of these handles would match, so we would need a compatible cover also. My main question is the operator. The main arm is probably the correct length, but what about that second arm? It is attached to the underside of the main arm and then goes to the bottom of the sash. I have seen egress operators with a second independant arm that clips to hardware on the sash, but this one seems to hinge off the main arm. Does your single arm operator accomlish the same functions? I can go back and get underside pictures and any necessary measurements before anything is ordered. But it looks like a potentially different operator. I am not familiar with the specifics of the ones in the field. I can get more info if warranted.

Thanks. -Kris

Regarding cover style and color, Truth unfortunately no longer makes operators like yours anymore. In recent years they've cut down on the available color options for their hardware considerably. In regards to the 39-013, this is only made in white, beige, bronze, and dark bronze. Your original colors are no longer in production.

As for the secondary arm, that's probably the hinge. This is a separate and distinct part and is not connected to the operator in any way. Unless you also need to replace the hinges, you can ignore it for now.

Okay. Dumb question- the hinge must be screwed in from the underside then, and not riveted? So we can just screw it into one of those holes on the operator base? I cannot tear apart the window trim to access the armature. Do you think this 13-1/2" ~has~ to be the correct size? I can go remeasure from any points X and Y that are visible, but cannot get at the base of the operator. Is/was there any other Truth casement operator size in the range of these, or would this be it? Even though it is short money, I don't want to wait till a contractor has her window torn apart to determine that these are wrong. I doubt the customer will care if the hardware is modernized, and I'm sure one of these colors will fly as long as I buy matching operator and handle. (Hadn't noticed that the operator covers are obsolete and come on the new operators. Thanks! -Kris H

The hinge is not attached to the operator in any way. It's a totally separate part. I'll share a video below that goes into more detail as to how a hinge installs and what its function is in the context of this window.

My suggestion of the 13-1/2" arm was based on your stated measurement of an arm that is approximately 14". If you have any doubts, you should disconnect the operator from the track and measure it to be safe. These are measured from the center of the plastic wheel to the center of the gear. Both of those details should be visible and accessible without having to remove the operator. If they're not, then you have to remove the operator. It can't be helped.

There is no other operator I'm aware of in this style with an arm that long, but don't guess. My advice is to take any steps you have to take to measure and verify. You never want to buy a part like this blind.

If the operator screw holes are obscured by the sill trim, then the trim will need to be pried off to access it.

Hi Tom, On Friday I went back out to the customer's home and verified the arm length. In the process, my parts list to order got longer. We will be ordering the hardware in beige. So we will be getting one operator for each side, as well as 2 folding crank handles and two of the sash tracks we discussed. But the customer now wants us to also get locks to match. I'm attaching a photo, but her locks have a 3" high square notch in the window framing. Assuming that they are handed, that would be two LH and two RH in beige. Additionally, as I stated, only one flanker currently operates. Since we do not know what speficically is failing on the RH casement flanker, she wants me to order her a set of hinges and hinge tracks. The hinges measure 5" end to end, and approx 4-1/2" center- to- center. The hinge tracks, top and bottom, measure 10". I am attaching photos from the (LH) operating flanker, but we would want these for the RH flanker. Again, I am attaching a few photos- one of the top and two of the bottom. Thanks. -Kris

Thanks for getting back to us. These locks are an old version of our 38-098 and 38-097. These should replace the old model but you might want to get the 38-079 keeper for both sides. I don't think the new style lock works with the old style keeper.

As for the hinge, as long as the base track is 10" long then our 36-048 will replace it. The size and configuration of the other arms don't matter so much since you're replacing the top and bottom at the same time anyway.
