Harken Protexit blocks are grommets designed to guide a rope through a deck or other structure while protecting the structure from abrasion and the rope from sharp edges. Available in five sizes: 30mm grommet (H1200), 30mm double grommet (H1201), 40mm (H1202), 50mm (H1203) and 60mm (H1204) — covering everything from light steering lines to larger, loaded trim lines.

The special feature of the Protexit series compared to regular blocks is the round, smooth-edged body designed specifically for through-hole use, which prevents the rope from rubbing against the edge of the deck or other structure when passing at an angle. The double model (H1201) allows two ropes to be guided from the same through-hole in parallel, which is useful in tight installations where there is no space for each rope to have its own hole.

The size selection is made according to the rope thickness and load — a smaller 30 mm block is sufficient for light steering lines, while 50–60 mm sizes are better suited for the main load-bearing trim lines of larger boats, such as the jib or headsail corner line.

When choosing the size of the Protexit block, it is important to consider both the rope thickness and the strength of the material at the penetration point — a block that is too small in relation to the rope causes unnecessary friction and accelerates rope wear, while an oversized block can be unnecessarily heavy and take up more space than is available at the installation site. The double penetration block (H1201) is especially worth choosing when two ropes pass through the same point in parallel and almost in the same direction, as it keeps both ropes neatly separated without them rubbing against each other as they pass. During installation, the size of the hole through the deck or other structure must be precisely matched to the block body so that the block fits tightly and cannot move during use, which could enlarge the hole over time and weaken the tightness of the structure. The smooth, rounded design of the Protexit series significantly reduces rope wear compared to a standard, sharp-edged penetration, which significantly extends the service life of both the rope and the block itself, even under heavy use.

It is a good idea to carefully seal the block's attachment point during installation to prevent water from draining through the penetration under the cover.

Choosing the right size ensures that the rope passes through the block smoothly without unnecessary friction or wear.

Regularly inspecting the block for wear, especially in heavily used passages, will extend the life of both the block and the rope.
