With over forty years of expe­ri­ence, we’ve found that even with the advent of tube read­ers” and sim­i­lar devices, it is imper­a­tive regard­less of the indus­try to have poka yoke fix­tur­ing on the shop floor for imme­di­ate inspec­tion and in-process activity.


Clark Fix­tures came into exis­tence because of the auto­mo­tive indus­try. Our first fix­ture was for check­ing a formed rub­ber radi­a­tor hose. There was also the need to check the tang ori­en­ta­tion for the clamps. That was our start. Today we ser­vice the domes­tic and for­eign auto­mo­tive indus­try around the world with fix­tures for fuel and brake-lines, exhaust tub­ing, HVAC, filler tubes, airbag tub­ing and many more. We are excit­ed to see what the future brings in the auto­mo­tive indus­try, such as elec­tric vehi­cles that have no steer­ing wheels and pedals.

It makes sense that an Ohio com­pa­ny is in this indus­try because of Ohio’s rich his­to­ry in aero­space and space. Our first for­ay into this busi­ness was pri­mar­i­ly pro­vid­ing check fix­tures that would incor­po­rate var­i­ous in-process capa­bil­i­ty to the lead­ing jet engine com­pa­nies of the world. We also helped design and build a unique prod­uct for man­u­fac­tur­ing cus­tom ven­ti­la­tion tubes for air­craft and space cap­sules. Our cus­tomers are look­ing for bet­ter and faster meth­ods of inspect­ing and man­u­fac­tur­ing engine and air­craft tube com­po­nents. From there we start­ed work­ing with com­pa­nies pri­mar­i­ly involved with mil­i­tary air­craft and then were asked to pro­vide in-process fix­tures for propul­sion tub­ing on the NASA Ori­on space cap­sule. Two years lat­er, we start­ed work­ing on life sup­port tub­ing for the manned Ori­on cap­sule. Since that time we have worked with a num­ber of select com­pa­nies doing excit­ing work build­ing rock­ets, engines and oth­er cap­sules for space. It has been a privilege!

Although not a large seg­ment of our cur­rent busi­ness, the med­ical indus­try is one that we serve. Pro­vid­ing a check fix­ture to ver­i­fy formed tub­ing and intramedullary nails and stays. The largest area of work is in med­ical equip­ment and fur­ni­ture. Our fix­tures are uti­lized to ver­i­fy bent tub­ing and var­i­ous fea­tures on the tube. In-process fix­tures have been also used for ver­i­fy­ing hole loca­tions and oth­er fea­tures. Where accu­ra­cy is need­ed, our prod­uct is the solution.

Recreational Vehicle

We have had the priv­i­lege of work­ing with numer­ous com­pa­nies, for­eign and domes­tic, that cre­ate and build vehi­cles Amer­i­cans hit the open road and trails on. From Harley motor­cy­cles to snow­mo­biles and ATVs, we have done it all. Our fix­tures have been uti­lized in the frames, bent rod stays, han­dle­bars and var­i­ous oth­er components.

The farm land of Amer­i­ca is one of our great­est resources. Clark Fix­tures is proud to sup­port many com­pa­nies involved in build­ing equip­ment to uti­lize this resource. In many cas­es we are involved in the tub­ing side of this equip­ment, but also have built pneu­mat­ic fix­tures to aide in robot­ic cells deal­ing with blow mold­ed and injec­tion mold­ed parts. We eat fresh and plen­ti­ful food because of these com­pa­nies. Thank you.

“We at Goodyear appre­ci­ate your quick response to requests for quotes and the man­u­fac­tur­ing of GD&T gages. Our cus­tomers are giv­ing us short­er and short­er lead times, which means we rely more and more on sup­pli­ers like you who are able to meet those reduced lead times. Of course, this also means that it is crit­i­cal for the job to be done right the first time, which is also a rea­son why we rely on a qual­i­ty sup­pli­er like you. This shows good orga­ni­za­tion, pro­ce­dures in place, and effort at all lev­els of your company.”
