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.
Applications
Primary mainsheet, halyard and spinnaker systems on boats to 12m (40ft)
Secondary mainsheet, vang systems on boats to 14m (46ft)
Standard and running backstay systems on boats to 10m (33ft)
General control line and lead block applications on larger yachts
Materials
Fully machined Alloy cheek plates
Alloy sheaves with captive ball races
Torlon® needle rollers
Carbon black Acetal ball bearings
Forged grade 17-4PH stainless steel shackles

After one use
Style: Lawn Edger/Tool Only
Not as powerful as I would have liked so the trim is not as smooth

Very good lawn edger
It does a great job and easy to create straight, clean lines. Does not do well going around curves.

Great value.
Works great, easy to handle, relatively quiet, and powerful enough to cut through 3 inches of sod.

Trim me up
The trimmer works as described. It arrived as promised, it manicured my 80 ft linear ft in no time. I ran 2 passes because I hadn’t done it in decades.

Great edger
This is a great lightweight and portable edger. It’s much easier to use than a gasoline powered model. The only limiting factor is the length of the electric cord. It does a great job and make sure your driveways and sidewalk look manicured.
