Originally established in Fremont California in 1972 by Steve Goldstein, and currently located in larger facilities in Herald, California, GKL Products has been developing both residential and commercial products for the lock and security industry.  Our "flagship" product, the Hinge Doctor, has been an effective and unique tool in the restoration of door hinges and has lead the way to new product development and release.

Now in our 34th year of operation, our product development continues to flourish.  A number of new products are in the final stages of development and release and will herald the ongoing drive to bring new products to the industry.  

  

All of GKL Products are designed with four objectives in mind:

  • Convenience for the installer
  • Value for the installer and the customer
  • Significant installation or repair time savings
  • Durability

At GKL Products, we have manufactured our products from the best materials available and only the highest quality craftsmanship has been put into our products. A purchase of a quality GKL Product is a choice for durability and value, which will pay off over time, every time.
