Lagoon bolts muaj ib tug ntse taw tes thiab ntxhib threads los muab lub siab tshaj plaws tuav nyob rau hauv ntoo, tab sis yuav tsum tau pre-drilled vim lawv txoj kab uas hla loj. Kev saib xyuas ntxiv yuav tsum tau coj los xyuas kom meej tias lub qhov pilot yog nruab nrab ntawm lub stud thiab tias lub qhov predrilled yog drilled li tob li tag nrho cov ntsia hlau yuav kawg.

Dab tsi yog square taub hau bolts siv rau:
qab beam
chaw nres tsheb ncej
TV phab ntsa mounted
hnyav kev tsim kho
Qhov hnyav npaum li cas tuaj yeem ua lag luam bolt dais *
1/4" lag bolt - 2 0" embedment qhov tob, 272 lbs. dawb huv
5/16" lag bolt - 2.5" embedment qhov tob, 368 lbs. dawb huv

Ua ntej sim laum lub qhov, nws yuav pab tau rau kais lub laum me ntsis uas muaj cov extraction me ntsis rau hauv lub qhov pilot nrog lub teeb rauj. Yog tias txhua yam ua tau zoo, txuas ntxiv rov qab mus txog thaum lub ntsia liaj qhov rooj raug tshem tawm, lossis koj tuaj yeem siv lub vise los tuav lub ntsia liaj qhov rooj kom tshem tawm tag nrho.
* Ntau npaum li cas tus ntsia liaj qhov rooj tuaj yeem tuav tau nyob ntawm ntau yam, suav nrog tab sis tsis txwv rau hom ntoo, xov qhov tob, thiab lub kaum ntse ntse.
