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 14m (46ft)
Secondary mainsheet, vang blocks on boats to 15m (50ft)
Standard and running backstay systems on boats to 12m (40ft)
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
Grade 316 stainless steel head post

No polarity and super bright.

Quick installation. Turned my halogen lights into led lights. No issues with polarity and no error codes. The license plate light shine much more bright than halogen lights. Amazing upgrade. Great price and highly recommend.

Affordable and hassle-free
Size: 921/912, Color: White
These reverse lights are super bright! The old bulbs left things practically pitch-black for night driving, total game-changer once these went in. Affordable, hassle-free upgrade that makes all the difference.
