    Product Information

    Orbit blocks™ are a no-compromise product range developed to meet the demands and expectation of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive Acetal ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio.

    Head posts of swivel blocks can be locked at 0 or 90 degrees.

    Just an ABSOLUTELY PERFECT Bar Cart!
    Style: Grey Oak, Size: 14.17"D x 37.01"W x 35.24"H
    Completely blown away with this cart! It FAR exceeded my expectations! A little more expensive than similar items, but the reviews sold me on it! Approximately 45 minutes to assemble from unboxing. Really good instructions. Tools included. I put together lots of these Lego Projects, so I can get through pretty quickly. This is a HEAVY, STURDY, SOLID, WELL MADE piece! All of the metal and wood surfaces are smooth and clean! Its much sturdier than it looks in the ad pics. It's also a little larger than I expected, even though I did measure it all out before ordering. I had ZERO problems building this thing. It's beautiful. Lines and surfaces are my base motif, and this fits the bill perfectly! Im not a big fan of the handle but I did go ahead and install. This cart fits seemlessly in with other furniture materials and fabrics. Can be tucked neatly into a tight space, or in my case ... is anchoring its own spot under some artwork somewhat solo along a large wall. You absolutely get your money's worth with this one. An absolute score with Two Thumbs Up!

    Good quality wine cart.
    Very sturdy bar cart and well made. Product came well packaged, with good instructions and even some extra screws. It is helpful to have 2 people putting it together. The only downside is the wine rack will not hold fatter bottles of wine but I added a small wine rack to the top.

    The cart is very functional and relatively easy to put together. I was also provided a great tip on the assembly that made it much easier.
