Le ndawo ye-Mound Lever yenzelwe i-aluminium alloy ehlala isikhathi eside ephethe ama-chrome abunjiwe, aqinisekise ukumelana nokugqwala okuhlala isikhathi eside. Ihlangana namazinga okuphepha kwe-ANSI Grade 3 futhi ihlolwe ngemijikelezo engaphezu kuka-250,000 yokusebenza okuthembekile. Idizayini eguqukayo ifanela iminyango yesokunxele- nangesokunxele, kanye ne-latch eguqukayo (2-3 / 8 "noma 2-3 / 4") ifanela iminyango 35mm-45mm ubukhulu. Kulula ukufaka isikulufu nje kuphela, lesi seed set sihlanganisa isitayela, ukuqina nokuvikeleka kunoma yimuphi umnyango.
