Dead-end fitting for a Code Zero halyard. Code Zero halyard with 2:1 purchaseTo boost the performance when using a Code Zero , the halyard load must be higher than what normal halyard boxes and stoppers can handle. Therefore, a 2:1 purchase needs to be arranged by fixing the dead end of the halyard in the mast and letting it run through a block attached to the halyard swivel. Position on the mast must be specified by Seldén. In most cases Code Zero sails need to be hoisted lower than gennakers and spinnakers. .cz-spec-wrapper { overflow-x: auto; margin: 20px 0; } .cz-spec-table { width: 100%; min-width: 700px; border-collapse: collapse; font-family: inherit; font-size: 14px; } .cz-spec-table th, .cz-spec-table td { border: 1px solid #e5e5e5; padding: 12px 14px; text-align: left; vertical-align: top; } .cz-spec-table th { background-color: #f8f8f8; font-weight: 600; } .cz-spec-table thead th { background-color: #111; color: #fff; font-weight: 600; } .cz-spec-table tbody tr:nth-child(even) { background-color: #fafafa; } .cz-spec-title { font-size: 18px; font-weight: 600; margin-bottom: 10px; } Code Zero Dead-End Fitting – Specification Comparison Specification 508-843-01R 508-844-01R 508-838-01R SWL (Safe Working Load) 1000 kg 2200 kg 3500 kg Max Righting Moment (RM) @ 30° 45 kNm 180 kNm 350 kNm Included Hardware 3 Monel pop rivets Ø6.4 x 17.8 mm 4 Monel pop rivets Ø6.4 x 17.8 mm 4 M8 screws (8x25 mm) Compatible Mast Sections E177, E206, C137, C153, C156, C175, C180, C192, C193, C208, C211, C227, F170, F176, F185, F194, F199, F212, F217, F228 E206, C225, C242, C245, C261, C264, C285, F234, F246, F252, F265, F272, F286, F291, F305 C280, C321, C365, F324, F370, F406
