{"product_id":"econoline-plastic-tread","title":"S.R. Smith Econoline Plastic Tread","description":"\u003cp\u003eThe S.R. Smith LTDF-101 is the Econoline replacement tread for pool ladders, molded in heavy duty plastic and recommended for residential ladders. It measures 3 in. deep by 18-5\/16 in. wide, with a 17-1\/4 in. centerline mounting distance, and is sold under the 19 in. Econoline size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMeasure before you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLadder treads look interchangeable and are not. The number that matters is the centerline mounting distance, the span between the points where the tread bolts to the rails. Measure that on the tread you are taking off and compare it to the 17-1\/4 in. figure here. Depth and width should be checked as well, but a tread that does not line up at the mounting points will not go on at all.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy not to put it off\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTreads take the whole load of someone climbing out of a pool with wet hands and wet feet, and plastic that has sat in sun and chlorine for years goes brittle before it looks bad. A tread that flexes underfoot, has hairline cracks around the bolt holes, or has lost its texture is the one part of a ladder worth replacing at the first sign rather than the last.\u003c\/p\u003e","brand":"S.R.
