Ingaphakathi leqabunga lesicabha lensimbi elingashi ligcwele izinto ezintsha zokunqanda amalangabi nezindawo ezishisayo, futhi izingxenye zobuso be-concave kanye ne-convex zenziwe ngemishini yobungcweti futhi zicindezelwa izinto zokunamathisela ezinobungani bemvelo. Umnyango ongashi uvalwe lapho kuhlangana khona iqabunga lomnyango kanye nohlaka lomnyango futhi eduze kwengilazi engashi, okuthuthukisa kakhulu ukusebenza komlilo.

Umnyango okalwe ngamahora angu-3,Imizuzu engu-60 yomlilo elinganiselwe iminyango eshelelayo,iminyango yokuphuma komlilo iyathengiswa, umnyango womlilo ongu-2040 x 826,crittall isitayela iminyango yangaphakathi umlilo ukalwe,iminyango yomlilo ehamba phambili, ukufinyelela kwe-attic okulinganiselwe umlilo,Umnyango okalwe ngamahora angu-3,umnyango olinganiselwe umlilo we-laminate, umnyango womlilo we-27,crittall isitayela iminyango yangaphakathi umlilo ukalwe,762mm umnyango womlilo,Umnyango okalwe ngamahora angu-3,umnyango wokuvikela ongenamlilo,Imizuzu engu-60 yomlilo elinganiselwe iminyango eshelelayo,926 umnyango womlilo,crittall isitayela iminyango yangaphakathi umlilo ukalwe,Iphaneli yokufinyelela elinganiselwe ihora elingu-1,Imizuzu engu-60 yomlilo elinganiselwe iminyango eshelelayo,Umnyango olinganiselwe umlilo weqabunga elilodwa
