Qhov tshwj xeeb coj qhov ntev yog raws li nram no:
An4: puab txoj kab uas hla = 5.56mm, sab nraud txoj kab uas hla = 11.18mm;
An6: puab txoj kab uas hla = 8.7mm, sab nraud txoj kab uas hla = 13.97mm;
An8: puab txoj kab uas hla = 11.11mm, sab nraud txoj kab uas hla = 16.26mm;
An10: puab txoj kab uas hla = 14.2mm, sab nraud txoj kab uas hla = 20.32mm;
An12: puab txoj kab uas hla = 17.46mm, sab nraud txoj kab uas hla = 23.50mm;
An16: puab txoj kab uas hla = 22.23mm
Nco tseg: vim hais tias lub raj sab hauv yog NBR roj hmab raj thiab elastic, nws yog ib qho tseem ceeb rau cov ntaub ntawv ntsuas kom muaj kev kam rau siab (Txawm tias cov khoom siv hlau siv nyob rau hauv qhov chaw foob pob hluav taws muaj kev zam, thov nkag siab).
Saib kab ID hauv cov lus hauv qab no kom paub meej (chav tsev ntawm kem ID yog nti, thiab yog tias nws hloov mus rau metric system, nws xav tau * 25.4mm, uas yog cov ntaub ntawv metric saum toj no)
