The profile is the same, the slope is the same, and the installation method is the same. The difference is in the overhang: 125mm of external leg versus 100mm gives a more prominent drip detail, a wider visual profile on the finished parapet, and a slightly more positive throw of water clear of the wall face below.

On a standard single-skin brick or block domestic extension with a parapet wall width of around 100-150mm, a 100mm external leg gives a balanced profile. On a wider wall, a cavity wall construction with insulation, or a commercial parapet built to a larger wall thickness, the 100mm leg can look narrow and under-scaled against the wall width. The 125mm leg gives a more substantial profile on these wider constructions and is more commonly specified on new-build housing developments where parapet wall thicknesses tend to be greater than on single-skin domestic extensions.

A 125mm minimum external overhang is common on new-build housing across the South East and the Home Counties, particularly on two-storey properties and on developments where the parapets are prominent in the streetscape.

On walls of this width, a 125mm external leg gives a better proportional profile and a more positive drip detail than the 100mm version.

The wider overhang casts a more defined shadow line below the parapet and produces a profile that reads more confidently at street level.

The only difference is the length of the external leg: 100mm on the narrower system, 125mm on the wider. The 125mm leg gives a more substantial overhang, throws water further clear of the wall face, and produces a wider visual profile on the finished parapet. It is better suited to wider parapet wall constructions, new-build housing developments where the housebuilder specification calls for a 125mm minimum, and projects where a more prominent coping profile is specified. All stopends, corners and accessories in the two systems are separate products and are not interchangeable.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003e\u003cspan\u003eHow do I calculate the correct stopend size for the 125mm system?\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAdd the wall width to 220mm. That figure accounts for the 125mm external leg, the 75mm internal leg, and 10mm returns on each side (125 + 75 + 10 + 10 = 220). A 215mm wide wall gives a stopend size of 435mm. A 290mm wide wall gives 510mm. If the result falls between two available sizes, order the next size up. Note that this formula gives results 25mm larger than the same wall width on the 100mm system (which adds 195mm rather than 220mm).

The end of the coping run on your left as you look at the wall needs the left handed stopend. The end on your right needs the right handed stopend. The handedness is fixed by the slope profile of the coping: the left handed stopend is fabricated to close the left terminal of the run with the end face following the slope in the correct direction for that end. Fitting the wrong hand reverses the slope at the terminal and means the joint will not close correctly.

The coating standard applies consistently across the 125mm system as it does across the 100mm system and the flat coping range: same specification, same colour range, same durability requirements. All components in an order are coated to this standard in the same batch.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eFor NHBC-registered new-build projects, Chapter 7.1 of the NHBC Standards sets out parapet wall and flat roof construction requirements. On new-build developments where the house type specification calls for a 125mm external leg sloping coping, the complete system from lengths to stopends is consistent with those requirements and supports the NHBC warranty position on completion.\u003c\/span\u003e\u003c\/p\u003e","brand":"Online Metal Store Ltd","offers":[{"title":"185mm","offer_id":42314558603348,"sku":"AC2-LHCS-125-185","price":59.52,"currency_code":"GBP","in_stock":true},{"title":"210mm","offer_id":42314558636116,"sku":"AC2-LHCS-125-210","price":60.48,"currency_code":"GBP","in_stock":true},{"title":"235mm","offer_id":42314558668884,"sku":"AC2-LHCS-125-235","price":61.44,"currency_code":"GBP","in_stock":true},{"title":"260mm","offer_id":42314558701652,"sku":"AC2-LHCS-125-260","price":62.4,"currency_code":"GBP","in_stock":true},{"title":"285mm","offer_id":42314558734420,"sku":"AC2-LHCS-125-285","price":63.36,"currency_code":"GBP","in_stock":true},{"title":"310mm","offer_id":42314558767188,"sku":"AC2-LHCS-125-310","price":64.32,"currency_code":"GBP","in_stock":true},{"title":"335mm","offer_id":42314558799956,"sku":"AC2-LHCS-125-335","price":65.28,"currency_code":"GBP","in_stock":true},{"title":"360mm","offer_id":42314558832724,"sku":"AC2-LHCS-125-360","price":66.24,"currency_code":"GBP","in_stock":true},{"title":"385mm","offer_id":42314558865492,"sku":"AC2-LHCS-125-385","price":67.2,"currency_code":"GBP","in_stock":true},{"title":"410mm","offer_id":42314558898260,"sku":"AC2-LHCS-125-410","price":68.16,"currency_code":"GBP","in_stock":true},{"title":"435mm","offer_id":42314558931028,"sku":"AC2-LHCS-125-435","price":69.12,"currency_code":"GBP","in_stock":true},{"title":"460mm","offer_id":42314558963796,"sku":"AC2-LHCS-125-460","price":70.08,"currency_code":"GBP","in_stock":true},{"title":"485mm","offer_id":42314558996564,"sku":"AC2-LHCS-125-485","price":71.04,"currency_code":"GBP","in_stock":true},{"title":"510mm","offer_id":42314559029332,"sku":"AC2-LHCS-125-510","price":72.0,"currency_code":"GBP","in_stock":true},{"title":"535mm","offer_id":42314559062100,"sku":"AC2-LHCS-125-535","price":72.96,"currency_code":"GBP","in_stock":true},{"title":"560mm","offer_id":42314559094868,"sku":"AC2-LHCS-125-560","price":73.92,"currency_code":"GBP","in_stock":true},{"title":"585mm","offer_id":42314559127636,"sku":"AC2-LHCS-125-585","price":74.88,"currency_code":"GBP","in_stock":true},{"title":"610mm","offer_id":42314559160404,"sku":"AC2-LHCS-125-610","price":75.84,"currency_code":"GBP","in_stock":true},{"title":"635mm","offer_id":42314559193172,"sku":"AC2-LHCS-125-635","price":76.8,"currency_code":"GBP","in_stock":true},{"title":"660mm","offer_id":42314559225940,"sku":"AC2-LHCS-125-660","price":77.76,"currency_code":"GBP","in_stock":true},{"title":"685mm","offer_id":42314559258708,"sku":"AC2-LHCS-125-685","price":78.72,"currency_code":"GBP","in_stock":true},{"title":"710mm","offer_id":42314559291476,"sku":"AC2-LHCS-125-710","price":79.68,"currency_code":"GBP","in_stock":true},{"title":"735mm","offer_id":42314559324244,"sku":"AC2-LHCS-125-735","price":80.64,"currency_code":"GBP","in_stock":true},{"title":"760mm","offer_id":42314559357012,"sku":"AC2-LHCS-125-760","price":81.6,"currency_code":"GBP","in_stock":true},{"title":"785mm","offer_id":42314559389780,"sku":"AC2-LHCS-125-785","price":82.56,"currency_code":"GBP","in_stock":true},{"title":"810mm","offer_id":42314559422548,"sku":"AC2-LHCS-125-810","price":83.52,"currency_code":"GBP","in_stock":true},{"title":"835mm","offer_id":42314559455316,"sku":"AC2-LHCS-125-835","price":84.48,"currency_code":"GBP","in_stock":true},{"title":"860mm","offer_id":42314559488084,"sku":"AC2-LHCS-125-860","price":85.44,"currency_code":"GBP","in_stock":true},{"title":"885mm","offer_id":42314559520852,"sku":"AC2-LHCS-125-885","price":86.4,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/1588\/2580\/files\/AluminiumSlopingCoping_6ca9c461-8e8c-4b6f-a9bc-66bc1123ec4c.png?v=1774517138","url":"https:\/\/onlinemetalstore.co.uk\/products\/aluminium-coping-stopend-left","provider":"Online Metal Store Ltd","version":"1.0","type":"link"}
