Clarke Systems, based in Allentown, PA, has been a wholesale manufacturer/supplier of interior and exterior architectural sign products to the signage trade for 40 years. You might say that the sign business is in our blood.


Owner Charles (Charlie) Kelly, Jr. has grown up in the industry with roots extending back to his grandfather who established a neon and electrical sign company in the early 1930s and manufactured and maintained signage programs for nationally branded businesses through the 1960s.


Clarke Systems -- formerly Spandex USA -- was started in the mid-70s by Charlie's father, Charles (Chuck) Kelly, Sr., who was among the first to introduce game-changing, modular signage to the US sign industry – the award winning Slatz® system of extruded aluminum faceplates and injection molded clips developed in Great Britain. Charlie has been at the helm for nearly 20 years, bringing on new products and services as he has grown the company.


Today the Slatz system is still a key element in our product mix. What customers continue to like about it is its excellent versatility: Available in straight lengths, cut-to-size, ready-to-finish kits or completed, ready-to-install signs, it can be produced in a near-limitless variety of configurations Extrusions are available in a silver anodized finish or a selection of industry colors using Clarke's proprietary Colorfix™ system. Slatz is suitable for everything from a basic directory or menu board to a broad scale wayfinding system.


Additionally, Slatz Capture™, a companion product, features extrusions that hold paper inserts with a clear ADA-compatible lens or rigid engraver stock, including acrylic, zinc, and photopolymer up to 1/16th inch thick. What makes this system unique is that unlike the curved paper-holding systems on the market, it has a flat profile that can be mounted individually or grouped on a simple clip system.


ADA, Wayfinding and Partnering Projects


Clarke Systems also offers a full range of ADA and wayfinding signage in both standard and custom designed formats. More than just a supplier, Clarke offers partnering assistance to our trade customers in sales support, proposal development, project planning & managing, and manufacturing. As examples, we have partnered with our customers on large-scale hospital, university and arena projects to name a few.
