Disappointment is the word how I feel. I don't know why I thought that because its a Wilton, it'll be much better than my current 60 years old shabby vice. Maybe because Wilton website is perfect, therefore you think, the products are perfect. I expected it to make me feel good. Nope. Hence, if you're considering this 21300 744 model, my advice No1 is to NOT have your hopes too high. The jaws will not meet parallel; one jaw will be higher than the other, on one side, but not on the other; there will be debris inside, in all joints and threads; and no grease on main screw; and scratches. My advice No2 is to re-consider buying a new vice or at least this vice. If I knew what low quality I would get, I would not buy it. I would just clean up and re-paint the old vice for $20 and be much happier. So unless your old vice cracked and fell apart, don't buy a new one. Advice No3 - revise your requirements for a new vice, don't look for 4 mounting points or for double-lockdowns or for something what you can't get. Because for Canadians, very little choice is made available, and what is available, like this 744 vice, is only sold by a single supplier and at 3 times the price. If by now, you haven't changed your mind, read my comments again - you will save yourself from huge disappointment. All in all I do not recommend this vice. New edit: forgot to mention, the jaw opening is NOT 4 1/2" as stated in the specs, but in actuality, the practical opening is 4" as the main screw disengages at 4 1/8". For me, not a big deal, but for someone else, could be a big surprise. New edit #2: discovered another surprise - mounting holes are of smaller diameter. In the specs, mounting hole is 9/16" and recommended bolt diameter 1/2". However, don't rush to buy 1/2", because it won't fit. The vice that I just received, has actual hole diameter 0.488", hence, 1/2 (0.5) inch bolt will be too big. Product dimensions can change without notice, and the drawings become outdated. I recommend you wait to receive the vice, then measure the actual hole, and then buy the bolt that fits the hole and not the drawings.
