I believe that the inner workings of the crank are stripped. Do you have replacement parts or do I need to replace the entire mechanism (if so, can you provide)? Thank you.

Please assist me in replacing the cranks shown in photos and crude diagrams. We believe the windows to be about 34 years old, Marvin brand. The broken portion of each mechanism is the rotating center part attached to the hand crank. It has come out, rotating on it's thread. It allows opening of the ... (cont.)

Hi. The casement window opener no longer will operate. I removed it and have attached photos. It is stamped with U.S. Pat #4505601 and there is another spot where it says 45142. It is a Truth part from, apparently, 1986. It has two spots where it fastens to the window. The length of the cross piece ... (cont.)

Need a replacement part for crank windows. Photo attached.

Looking for this window mechanism. The window is a Marvin awning about 44" X 16", with a glass date of 2001. Stamped on the bottem is "Truth #45002". I would prefer a white operator cover and also would need a white crank. Will take what color is available. Thanks for your help.

I have a pair of awning windows that won't open because of a subsequent installation of hot water baseboard heating that blocks the Lever. Is there an alternative operator I could replace them with, either a crank or offset lever? I broke the lever trying to bend it enough to clear the heating cove ... (cont.)

Please help me determine the correct operator to order based on the attached images. Thank you!

Lock for Truth 40538 and replace the arm. I'm not sure which arm order. Attached are some photos, I believe the arms measures between 14"-16".

I have to order 2 more 39-239B I also need 2 that have the crank in the middle of the unit and it extends 8 inches or so. Same clips as 39-239B

I have rusted out hardware on my single awning windows. I have added pictures of the parts we removed. There are 2 locks per window, with the white levers. There is one hexagonal metal piece with a handle that opens the window. And there is a separate metal unit I placed next to the locking mechanis ... (cont.)

Hi, The crank on our awning operator is damaged, so we need a new one. I looked on the web site, but couldn't find an exact match for the one we have. Any help in identifying the correct part would be appreciated. I've attached photos of the operator. The bar attached to the window is 13 1/2", an ... (cont.)

Windows are Alside U1000, circa late '90's. Straight cranks protrude too far and interfere with blinds. Crank is 3 1/16" L. Looks like 40085 stamped inside. Attaches to window with 12 splines and set screw. Dia. across splines is approx. 0.326". I was looking at Truth 39-205, but don't know if splin ... (cont.)

The hardware says Entry Guard Truth and 20810

Aloha,Please let me know if this type of awning crank is still available, or a suitable replacement. The Milgard windows were installed in the early 90's with a stucco exterior and plaster interior, so we would like to avoid having to replace the entire windows.The side "hinges" need to be replaced ...

Hi. I have a video of this crank in action. It will open the window, but on reversing the direction of the crank, it just unscrews itself, and the window does not move. I can close the window by pushing from the outside while lightly turning the crank inside.

The window crank housing threads for the brass retainer appear to be worn and damaged so will not lock in the main crank stem.

I need replacement crank assembly for my marvin casement window. The spread of the arms when closed is approx 23". The crank is in the center of the window at the bottom. The crank doesn't close the window, instead the handle threads itself out of the housing
