#Knock knock cast series#
This was blamed on the loss of several main cast members, a change in the format and the overall look of the series which changed dramatically following an overhaul by ITV executives in 1999. The series was axed in 2001 following poor viewing figures for the final series. The series also adopted a number of different formats: while the early series interspersed various storylines and had running plots across the series later series adopted a multi-part format resulting in two or three cases per series while the final series adopted a stand-alone week by-week format. The only three cast members to appear in every series were Caroline Lee-Johnson, Trevor Byfield and Steve Toussaint. The series had a rotating cast, with only a small number of cast members appearing throughout the series' run. The series derived its name from the distinctive " Knock knock knock" command used over the radio to synchronise a raid.įive series were broadcast from 10 April 1994, until 11 November 2000.

We have built a strong reputation for quality workmanship and excellent customer service. Harper Precast has provided flexible and durable concrete knock-out boxes and other precast forms throughout Utah and the Intermountain West since 2006. Pre-casting concrete boxes allows for a more freedom in design and a more economical and environmentally responsible fabrication process as well.įinding a precast provider in your area who can supply the strong concrete boxes your structure needs will help you take care of an important detail of your project with as little stress and as much quality work as possible. This also helps the fabrication process run more smoothly because work can be done regardless of the weather conditions. Concrete that is mixed correctly and without interruption will cure to create the strong concrete knock-out boxes needed to build a solid structure. Because pre-casting takes place off site, it can be done inside to avoid exposing the curing materials to the elements.

One important benefit that using the precast fabrication process can provide over onsite fabrication is quality control. Enlisting the help of precast providers to build your project’s concrete boxes will generally yield the best results for a number of reasons.
The quality of workmanship used to fabricate concrete knock-out boxes is also an important factor that determines their strength. This is why you will most often find these boxes made from concrete that has been reinforced with a mesh knit material for extra strength. Because their ability to hold large amounts of weight is so critical, they must be made from the most durable materials possible. They can also be used to build several different holding tanks and storage spaces. They play an important role in the construction of a variety of large structures including underpasses, service tunnels, subways, outfalls, and bridges. Concrete knock-out boxes come in a variety of shapes and sizes depending on the intended use.
