Abstract
A means for the vertical or height adjustment of folding doors comprises a pivot pin assembly utilizing a threaded adjustment bolt with a separate, unthreaded pivot pin. The bolt is threaded into the sleeve above the pivot pin. A lower interior portion of the sleeve includes a polygonal interior cross-section which matches the head of the pin and prevents the pin from rotating. The pivot pin may be held within the sleeve during shipment and installation by a friction fit with a cap positioned in the bottom of the sleeve, or instead a spring may be used between the pivot pin and cap to urge the pin upwardly. Rotation of the bolt vertically adjusts the pin.
