isango elijikahlelayo locingo lukagesi linebhokisi lezindlu elivikelekile, elisetshenziselwa ukufaka amasango noma iminyango eguquguqukayo ngokushesha. i-polytape noma i-polyrope izobuyiselwa ngokuzenzakalela ebhokisini lezindlu elivikelwe, elilula nokuphepha ukuvula noma ukuvala isango locingo. izingxenye ezihlanganayo, izikulufo nezibambo zamasango zifakiwe ukufakwa ngokushesha futhi kalula. izingxenye zokugquma zisetshenziselwa ukuxhasa isango eli-retractable roller, izikulufo zisetshenziselwa ukukhweza kokuthunyelwe ngokhuni, ucingo lusetshenziselwa ukuxhuma i-polywire noma i-polytape ezansi kwesango eli-retractable roller (kukhona umqhubi kagesi ezansi yesango elihoxekayo), lapho isango locingo livalwa ngesango elihlehlekayo, ishayela likagesi lizodlula lisuka kolunye uhlangothi luye kolunye.
