Tech-Tool Plastics, Inc. has been in the plastics business for more than 45 years. We began by designing plaster mockups and precision fiberglass aircraft tooling for other companies in the aviation industry. We then turned to manufacturing helicopter replacement windows. We saw a need in the industry for high quality windows that were affordable. Our extensive tooling expertise produces windows that fit perfect every time, requiring little or no trimming and extending the life of the transparency. This quality meets and exceeds that of the OEM and results in significant savings in installation time and labor to our customers.

Tech-Tool manufactures a full line of replacement windows for Airbus, Bell, MD Helicopters, Robinson, and Schweizer. Our sole business is providing replacement windows, allowing us to focus all of our efforts on creating the best product available. In addition to standard windows, we have developed many exclusive specialty windows not offered by other manufacturers. These windows enhance many helicopter operations and fulfill specific requirements requested by our customers. They include custom photography and observation windows, as well as “Cabin Comfort” windows which enhance cabin space.

Tech-Tool Plastics designs, manufactures, and stocks a complete range of standard and custom windows that are optically true while fitting and working beautifully. In addition to our standard windows, which are available with pop-out air vents, vertical or horizontal slides, and in clear or tinted (in a variety of colors), Tech-Tool Plastics offers an array of specialty windows.

Clear or tinted? It’s up to you – all of our standard and specialty windows are available in standard Clear or custom tints: Blue, Dark Blue, Dark Green, Smoke Gray, Light Gray, Bronze or Dark Gray tinted acrylic.

Quick change rubber mounted windows - these windows mount with a rubber seal and can be used as a replacement for traditional rivet-in installation. These windows save installation time by eliminating rivets and repainting.

Looking for slides? If needed, we are happy to manufacture replacement slides that will perfectly fit our windows. All we need is the TTP part number. Please specify if LH or RH, and tint. We will install a handle on your replacement slide and will provide the felt necessary for installation.
