Imodeli ye-T3200 kunye ne-T3300 ziiprofayili ze-aluminium ezisebenza njengendibaniselwano phakathi komgangatho kunye nesigqubuthelo sodonga.Inkcazo yobugcisa "yiprofayili yekona yococeko" kwi-akhawunti yesimo se-convex ye-convex, kwaye yenzelwe ngokuhambelana nemigaqo emitsha yezempilo kunye nococeko lwe-EU.Uyilo lususa i-angle ye-90 ° ukukhusela ukungcola - umthombo webhaktheriya - ekwakheni, ukudala indawo egobileyo eyenza ukucoca imihla ngemihla kube lula kwaye kusebenze ngakumbi.
