What the Jack JK-T1900G and JK-T1903G catalogue covers
Two pages in English: the cover, then the features, the bartack and button pattern charts and the specification tables. The tables cover the GS, GH and GM bartack builds, the K versions that also sew buttons, and the GR button sewer with automatic feeder.
The standard builds of both machines measure 805 × 405 × 525 mm, so they fit the same table layout. Al Borj supplies, installs and services both from Sharjah and Accra, in the UAE, the GCC and Africa.
