Henry Lindsay
Original 1930s Lindapter Logo

Lindapter was born in 1934 when Bradford engineer Henry Lindsay (1873 – 1954) invented an entirely new concept of connecting steel – simple and fast clamping as apposed to often difficult and time consuming drilling or welding. The idea that was to revolutionize millions of future connections on countless projects spanning the globe was not dreamt of overnight, rather shaped by Lindsay’s previous experience coupled with his inventive mind.

Henry Lindsay was a prominent and widely travelled engineer and specialized in the design of power transmission technology, destined mainly for the wollen mills of Yorkshire and the cotton mills of Lancashire. His career had blossomed at Crofts, a large Bradford manufacturer of the time, but an entrepreneurial drive destined Lindsay for greater accomplishment.

Lindsay identified the difficulties of securing manufacturing equipment to cast or wrought iron beams by drilling or welding and challenged these traditional methods with a startlingly overlooked solution; to simply clamp equipment to the structure instead.

The determined engineer decided to take advantage of this gap in the market and responded to the opportunity by setting up his own business with his wife Bertha and son Lawrence, founding Henry Lindsay Ltd. The company’s first office was located in the adjoining house to Lindsay’s in Queens Road Bradford, so he would have found the daily commute to be very short indeed!

Lindsay’s pioneering design was realized in 1934 with the launch of the Lindsay Bolt Adapter, a single casting that converted an ordinary bolt into a hook bolt. The adaptor clasped an iron beam flange and with the nut firmly tightened, securely connected equipment to steel. The unique solution quickly gained an established popularity and combining the two words ‘Lindsay Adapter’ explains the formation of the now famous brand name.
After the first year of operation under the newly created brand, there was need for both the expansion of staff and the necessity of a works. The ever-practical Lindsay arranged to share a building in Northfield Place, Bradford only 300 yards from the office in Queens Road.

During the war years the company prospered with more and more people recognizing the inherent advantages of clamping over site drilling or welding, particularly where temporary structures were required. Applications varied widely but they were used on Bailey Bridges, Mulberry Harbours and even PLUTO (Pipe Line Under The Ocean) used to supply fuel to the allied invasion forces in France.

Unfortunately, just as the post war recovery was complete and the success of the company was assured, Henry, now in his 80’s died but the company continued under his son Lawrence Lindsay.

Slowly the product balance shifted so that by the late 1960’s the vast majority of sales were for Lindapter connectors leaving the power transmission business behind until it was finally axed completely. Since then,  Lindapter has continued to expand and prosper with a change of company name en-route as well as several moves to larger premises but still within the Bradford area, finally settling at the current location in Brackenbeck Road.

The vast product range has diversified from the original 1934 invention of the malleable iron hook-bolt adapter. Today the distinguished array of products includes steel, hollow section (HSS), concrete decking, pipe / conduit supports and steel floor connections, in addition to custom design product development. Lindapter clamping systems are used throughout the world, on widely varied projects ranging from applications on bridges in Australia and Portugal, tea plantations in India, grain elevators in Argentina.

Lindapter has passionately grown over 75 years from modest beginnings to a reputable global brand and strives to continue its proud heritage; to invent and deliver ‘Technical Innovation in Steel Connections’.
