Rowan 4.1S / 20mm is a classical and the most simple model of a weblock with dumbbell-shaped captive pin.

For 20mm width webbings.

Differs from model 4.1 in miniature size. Even the smallest leashring will pass through such a weblock.

There exists a theoretical (extremely low) possibility for captive pin leaving its position during use on slacklines with very low tension and sudden high-amplitude fluctuations.

For lines with higher risk factor it is preferable to use weblocks with quick-release push-pin: Rowan 4.2 and Rowan 4.3

Rowan weblocks are made of high-strength structural steel. The center diverter is reliably welded to the side plates of a weblock. While following the curve of the center diverter with a diameter of 25mm, webbing loses almost no strength, in contrast to more primitive locking mechanisms or knots, where loss of strength is significant.

Smoothened edges reduce wear of webbing.

Design of Rowan weblocks is optimized in a way that maximizes effectiveness of load distribution. This has allowed for the weblock to be excessively strong, while remaining relatively lightweight.  

Attachment to the anchor point or sling is made using a steel shackle.

Additional omega-shaped steel shackles are required for incorporating soft-release into the system.
