I te piki haere o te hiahia mō te pumau me te pakari o ngā tūāpapa i roto i te hangarau hanga, ko te Mata Ledger hangai i roto iPūnaha tūāpapa Cuplockkua noho ngā taputapu hei arotahi hou i roto i te umanga nā tōna mahi tino pai. He hototahi tēnei taputapu ki tePūnaha raka kapuhe 48.3mm te whānui, ā, he mea hanga ki te rauemi Q235 mā te tukanga hanga mate. He kaha teitei, he ātete hoki ki te pakaru, ā, ka honoa ki ngā wāhanga pēnei i te Top Cup me te Bottom Cup i roto i te raupapa kotahi. Ka taea e ia te whakatutuki i te huihuinga tere me te hononga pumau o te tūāpapa, ka whakapai ake i te whai huatanga o te hanga me te tauwehenga haumaru i roto i te hanganga, te piriti me ētahi atu āhuatanga hangarau.

I tēnei wā, ka tautokohia e te Mata Rehita Hangaia ngā tukanga maimoatanga mata maha, tae atu ki te tae taiao, te hiriwa kua whakakikoruatia, me ngā momo koura kua whakakikoruatia, me te whakarato i ngā whakaritenga rahi me te taumaha tika (taumaha kotahi 0.21kg/0.25kg) hei whakatutuki i ngā hiahia ritenga o ngā kaupapa rerekē. Ko tōna hototahi ki te rino maka ngāwari me ngā taputapu maitai waro-iti ka whakarei ake i te hototahi me te whaihua o tePūnaha tūāpapa Cuplock, e whakarato ana i tētahi otinga tautoko pono ake mō te hanga hangarau.
