Abakaki bayingxenye ebalulekile yokufaka nokufaka ama-blind.Abakaki babamba amakhethini ngokuvikelekile endaweni oyifunayo, kungakhathaliseki ukuthi udonga, ifreyimu yefasitela noma usilingi.Bahlinzeka ngokuzinza nokusekelwa, babambe izimpumputhe endaweni futhi bavimbele ukuba bagweme noma bawa.Kunezinhlobo ezahlukene zamabakaki, njengabakaki abafaka ngaphakathi, asetshenziselwa ukufeza ukubukeka okuhlanganisiwe ku-recess yefasitela;abakaki bangaphandle abafakayo, abahlinzeka ngokufaka okukhulu ngaphandle kohlaka lwefasitela;kanye nobakaki osilingini, asetshenziselwa ukufaka amakhethini ophahleni olungaphezulu.Ngokufaka amabakaki ngendlela efanele futhi uwavikele ngezikulufo noma ezinye ihadiwe, izimpumputhe zihlala endaweni futhi zisebenza kahle, zivumela ukusebenza kahle nokulungisa izimpumputhe njengoba kudingeka.
