    I have 3 Entry Guard windows that need new operators. The Arm has 31538 on it. 2 of the windows open to the left and one to the right. Can you please give me some advice on what parts to order? I also need pricing.

      Jacob,
      The number 31538 is found on at least 5 different Truth Entrygard Operators. Do you have an number like 20810, 20755, 20544, or 20748 stamped on the linkage arm? The linkage arm is the arm that attaches to the bracket on the hinge side of the window. If you do not find a number you can email me a picture of the operator with the window open so I can see the arms and how they attach to the window. You can do this at https://www.homewindowrepair.com/contact-us .

    Hello,
    I’m Looking for a replacement for a Truth single arm operator. I don’t know the window brand. The unit has L30841 stamped on the arm, the length of the arm is 4 7/16″. One gear has 30843L on it, and an arm that connects to a slide on the bottom of the window to the window sill has 30744 stamped on it. The window does not hinge on the corner, rather slides as you crank open.
    Can you tell me the replacement part please? It looks like your part # Wi1510, but the Wi1510 has two arms, and my unit only has one arm. The track on the sill has 30751 stamped on it.
    I have pictures of all this, but don’t see a place on this site to post them.

    Thank you in advance for any help.

    Dan.

      Dan,
      My guess is you have the older version of the Truth Entrygard Dyad Operator. The Dyad operator is the same as the Dual Arm operator, except for the longer arms (10″ arm). Just to make sure, can you send me a picture to sales@robertbrooke.com ? The number 30744 is a number we find stamped on the hinges, you would find this number on the top and bottom hinge. The number 30751 is also a number we find on window hinges.

    How do I remove the small arm (31538) of my dual arm window crank?

  6. Jasmine says:

    Hi,

    I am looking to replace a part to replace, I have the parts 31538, 20755 and the part that needs replacing is stamped 45179. I can open my window but cannot close it because the knob comes loose when I try to close the window.

    I cannot find that part 45179.

    Please respond.

    • rbaadmin says:

      Jasmine,
      My guess is you need the Truth Entrygard Operator 20755. The numbers we find on these operators are just stamping and casting numbers, which lead us to make educated guesses on what you have. The stamping number help the most, they start with the number 2 or 3, the numbers that start with 4 are casting numbers, and they are usually no help. What has happened with your operator is the worm gear has popped. When you crank the window open the gear pushes down and is held in place. When you go to open the window, the gear tries to move outward, because you do not have the mechanical leverage.

    Hi, I need to replace the bottom hinge of my vinyl window. The hinge was stamped and states its a Truth 30751 B. The length of the hinge is 10 inches long and has three drill screw holes along the bottom. What replacement part can I use?

  11. BLM says:

    Hi, I need a set of Left and Right casement window operators for Truth hardware. Windows are Kolbe and Kolbe (K&K). I believe they are Dual Arm operators based on a catalog of parts. They have stampings of 20810 on link (link offset up I believe, which is about 4.5″, long arm is stamped LH 30470 and is about 9.5″ long, there is a stamping 40471 and the short angled arm is L30841. Catalogs show these I think as TH 23076 and TH 23077. Can you please advise and Thanks Robert!
