For these we collected every cleat of this style, discarded the features we didn't like, and incorporated those we did. We think that results in a chunky, effective cleat, and hope you agree. The 3" has a closed base, all the larger cleats have an open base.
The suggested lengths are listed with each size, and within reason you can have what you like since we don't supply the wood that goes with them. Please note also that the little lugs on the underside of the bar should - as in the picture - face outwards. The reason for this is that if a line is surged fast around the cleat, it won't saw the end of the cleat off. Too many versions of this product don't have the lugs at all.
A good general purpose cleat, which suits most styles of craft in most applications.
The teak ones are a bit more "yachty" than the ash cleats. They come with small holes drilled in them, which you ought to make bigger.
The ash, are of the chunky style, supplied without fastening holes, so you can make them fit the space where the last one fell off.
