01Identify the neck before selecting a sprayer
For KRN-0538, request the neck finish drawing, dimensions and tolerances for the actual bottle specification. The 29mm width body footprint does not identify a neck size. Keep the closure method and filling equipment requirements in the same review.
02Check the complete height stack
This reference lists 138mm bottle-body height and 164mm overall height. Use those two published values to compare the pictured arrangement. Do not treat their difference as the exact cap height or a guarantee that a replacement pump will fit.
03Separate the outer finish from the internal fit
For the pictured wood-look direction, confirm the actual material and finish as well as the insert dimensions. Inspect seating and removal with the selected pump; appearance alone does not establish either material or compatibility.
04Define functional checks with the sample
Send the intended fill product and application requirements with KRN-0538. Ask which priming, spray, dip-tube, seal and leakage checks are appropriate for that fill and assembly. Agree the test method and acceptance criteria before approving the component set.
