Rough-in on HSJ-2427 is chosen from 3 printed S-trap values: 250, 300 and 400 mm. Each printed value is a separate S-trap version of the same body. The catalog also lists a 180 mm P-trap version for wall wastes. Each pairing becomes an RFQ line. Confirm against the model spec sheet before the order is released, and keep the survey with the purchase file.

Siphonic and washdown are both offered on HSJ-2427, confirmed at quotation. A bathroom program with one house standard sets the same flush version on every line. A mixed program splits lines by room type. White ceramic and the floor mounted design stay fixed. Request written confirmation from the factory of the flush version and toilet count on each line before shipment planning begins. Writing flush beside outlet on the schedule keeps both visible to the site team.

Width on HSJ-2427 is 390 mm (15.4 in), and height is 750 mm (29.5 in). Length is 700 mm (27.6 in). Siphonic and washdown versions share this printed size, with S-trap rough-ins of 250, 300 and 400 mm and a 180 mm P-trap outlet. Verify against the official technical drawing before fabrication. The 28 inch label rounds the 27.6 in length.
