Beta Tools Copper-Berillium (Cu-Be) Spark-Proof Tools are specifically designed for safe operations in environments subject to potential risk of explosion, in the presence of flammable liquids and gases, or for any applications that require using perfectly antimagnetic, corrosion-resistant tools.All tools are certified by the Federal Institute for Materials Research and Testing (BAM) under European Directive 99/92/EC.Warning! Risk of explosion in ACETYLENE environment. The mechanical characteristics of spark-proof tools differ from those of normal steel tools. They should be used with extreme caution, avoiding overloads..tg {border-collapse:collapse;border-spacing:0;}.tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}.tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}.tg .tg-5ua9{font-weight:bold;text-align:left}.tg .tg-s268{text-align:left}.tg .tg-0lax{text-align:left;vertical-align:top} Beta Tools - Spark-Proof Double Open End Spanner Range Product Code Part Number Size A A1 L S Weight mm mm mm mm mm g 000550801 55BA 6X7 6 x 7 14 17.5 90 4.3 21 000550802 55BA 8X9 8 x 9 20 24 100 6 38 000550795 55BA 8X10 8 x 10 20 22 100 5.9 34 000550797 55BA 9X11 9 x 11 22 26 110 6.3 50 000550803 55BA 10X11 10 x 11 24 28 120 7 62 000550804 55BA 12X13 12 x 13 28.5 30 130 7.5 91 000550799 55BA 13X14 13 x 14 30 33 133 7.2 80 000550805 55BA 14X15 14 x 15 32 34.5 145 8 106 000550806 55BA 14X17 14 x 17 31 37 150 7.9 120 000550807 55BA 16X17 16 x 17 35.5 40 165 9 140 000550809 55BA 18X19 18 x 19 36.5 41 170 9 159 000550811 55BA 20X22 20 x 22 47 42 185 10 210 000550813 55BA 21X23 21 x 23 46.5 49.5 210 10 260 000550815 55BA 22X24 22 x 24 46 49.5 210 10.5 255 000550817 55BA 24X26 24 x 26 49.5 55 230 12 360 000550818 55BA 24X27 24 x 27 49.5 55 230 12 363 000550819 55BA 25X28 25 x 28 49.5 55.5 230 12 360 000550820 55BA 27X29 27 x 29 55 61.5 246 13 490 000550822 55BA 30X32 30 x 32 62 66 265 15 580 000550826 55BA 36X38 36 x 38 80 84 320 16 1376 000550828 55BA 36X41 36 x 41 73 83 335 16.4 1350 000550829 55BA 41X46 41 x 46 84 95 355 19.5 1741 000550830 55BA 46X50 46 x 50 93 101 370 18.6 1820 000550831 55BA 50X55 50 x 55 101 111 385 20 2185 000550832 55BA 55X60 55 x 60 111 121 415 21.5 2790
