This item is an excellent product and at a very competative price when compared to other sellers.
I would certainly purchase this or similar item again.
I ordered these rails as a replacement setup for my home made panel saw. They arrived in good condition with all of the parts. The pillow blocks fit perfectly and run along the rail smoothly. They aren_ as smooth as high end blocks, but you can_ beat the price.
Vše v pořádku, funkční. Jen nesmí být člověk překvapený, že v hliníkové podložce drží tyč jen dva šrouby. Pokud bude odpovídající zatížení pouze shora, neměl by s tím být problém.
