Nyob rau hauv xyoo tas los no, nrog kev txhim kho kev ruaj ntseg hauv cov chaw ua si, cov chaw siv hluav taws xob, cov chaw khaws ntaub ntawv, thiab cov chaw tsim kho hauv nroog tseem ceeb, cov laj kab hlau tsoos tau dhau los ua tsis txaus los ua kom tau raws li qhov xav tau ntawm kev tiv thaiv siab -. Anti-nce toj kev ruaj ntseg laj kab nrog siab- cov qauv mesh ntom ntom tau dhau los ua ib qho ntawm cov khoom lag luam tseem ceeb hauv thaj tsam ib puag ncig fencing.
Nyob rau hauv kev lag luam fencing thaum ntxov, cov pa ob - hlau laj kab lossis thav duab laj kab, vim lawv qhov loj mesh loj, yooj yim tsim cov ntsiab lus leverage, ua rau muaj kev phom sij rau kev nyab xeeb.

Anti-nce kev ruaj ntseg laj kab, los ntawm lawv cov mesh qauv tsim (cov lus qhia tshwj xeeb 75 × 12.5mm), txo qis qhov ua tau nce siab. Qhov ntom ntom kab rov tav steel hlau tsim ua rau muaj qhov nyuaj ntawm kev txiav, ua rau kev tiv thaiv tag nrho kev ua tau zoo tshaj li ntawm cov laj kab zoo tib yam.
Cov kws tshaj lij hauv kev lag luam taw qhia tias me me - cov qauv aperture tau dhau los ua ib qho tseem ceeb ntawm kev ua haujlwm siab - kev ruaj ntseg fencing.
