    This is the second set of adjusters I have bought from Kilian's. These things are pretty hard to find. Great service, great product. Glad I found this company.

    Operable wooden storms!

    These brackets are working well for my new wooden storms. They don't come with installation instructions, but you can find them here in the item description. I wish there was a way to adjust how tightly they pull the storms against the blind stops. Slotted holes on the jam brackets would be great.

    I ordered 15 sets of these window adjusters for our wood storm windows that we constructed this summer. Very well made and easy to install and made our storm windows much more secure. I will be back next year to order more.

    Excellent customer service! My only very small complaint is that they didn't ship it as quickly as I expected, but the product did get to me in a timely manner. I have since shared with my handyman and others that Killian's is the only place in the US that is still selling vintage hardware for hanging screens.

    The storm window mounting hardware that I purchased was shipped promptly and arrived in good condition. These items are not readily available from most suppliers and Kilian stands out by selling them...and at a very reasonable cost. Kilian will be the first place I go to in the future if I have a need for similar items.

    I ordered hardware for old fashion wood storm windows that isn't available locally. Your website was easy to use and your service was very speedy. I've done business with you in the past and was very satisfied then. I just wish you'd open a store in my area. Great job.
