Fisheries offers Harken 27 mm Traveler Track in three styles: standard low beam with 100 mm spaced mounting holes, "retrofit" low beam with 4" spaced mounting holes, and high beam with sliding bolt/variable mounting hole spacing.
This group is the standard low beam track - with 100 mm (3-15/16") mounting hole spacing.
27 mm Midrange CB (Captive Ball) Track is made of tough 6061-T6 aluminum that is Hardcote-anodized black with Teflon® impregnation for durability and easy ball bearing movement.
Use a standard low-beam track when the track can be supported at each fastener hole. Pinstop holes are spaced every 100 mm (3-15/16") between the fasteners (the first fastener hole is 50 mm [1-15/16"] from the end of the track.)
"Retrofit" low-beam track is designed as a direct replacement for older track designs (like Nicro Fico) with 4" spacing between fastener holes (the first hole is 2" from the end of the track).
Use a high-beam track when the track must span a cockpit or other unsupported area. Refer to the 27 mm High-Beam Track Spanning Chart in the High Beam Track entry for details; see Related Products, below.
